-``>>>``
- The typical Python prompt of the interactive shell. Often seen for code
- examples that can be tried right away in the interpreter.
-
- .. index:: single: ...
-
-``...``
- The typical Python prompt of the interactive shell when entering code for an
- indented code block.
-
- .. index:: single: BDFL
-
-BDFL
- Benevolent Dictator For Life, a.k.a. `Guido van Rossum
- <http://www.python.org/~guido/>`_, Python's creator.
-
- .. index:: single: byte code
-
-byte code
- The internal representation of a Python program in the interpreter. The byte
- code is also cached in ``.pyc`` and ``.pyo`` files so that executing the same
- file is faster the second time (recompilation from source to byte code can be
- avoided). This "intermediate language" is said to run on a "virtual machine"
- that calls the subroutines corresponding to each bytecode.
-
- .. index:: single: classic class
-
-classic class
- Any class which does not inherit from :class:`object`. See *new-style class*.
-
- .. index:: single: coercion
-
-coercion
- The implicit conversion of an instance of one type to another during an
- operation which involves two arguments of the same type. For example,
- ``int(3.15)`` converts the floating point number to the integer ``3``, but in
- ``3+4.5``, each argument is of a different type (one int, one float), and both
- must be converted to the same type before they can be added or it will raise a
- ``TypeError``. Coercion between two operands can be performed with the
- ``coerce`` builtin function; thus, ``3+4.5`` is equivalent to calling
- ``operator.add(*coerce(3, 4.5))`` and results in ``operator.add(3.0, 4.5)``.
- Without coercion, all arguments of even compatible types would have to be
- normalized to the same value by the programmer, e.g., ``float(3)+4.5`` rather
- than just ``3+4.5``.
-
- .. index:: single: complex number
-
-complex number
- An extension of the familiar real number system in which all numbers are
- expressed as a sum of a real part and an imaginary part. Imaginary numbers are
- real multiples of the imaginary unit (the square root of ``-1``), often written
- ``i`` in mathematics or ``j`` in engineering. Python has builtin support for
- complex numbers, which are written with this latter notation; the imaginary part
- is written with a ``j`` suffix, e.g., ``3+1j``. To get access to complex
- equivalents of the :mod:`math` module, use :mod:`cmath`. Use of complex numbers
- is a fairly advanced mathematical feature. If you're not aware of a need for
- them, it's almost certain you can safely ignore them.
-
- .. index:: single: descriptor
-
-descriptor
- Any *new-style* object that defines the methods :meth:`__get__`,
- :meth:`__set__`, or :meth:`__delete__`. When a class attribute is a descriptor,
- its special binding behavior is triggered upon attribute lookup. Normally,
- writing *a.b* looks up the object *b* in the class dictionary for *a*, but if
- *b* is a descriptor, the defined method gets called. Understanding descriptors
- is a key to a deep understanding of Python because they are the basis for many
- features including functions, methods, properties, class methods, static
- methods, and reference to super classes.
-
- .. index:: single: dictionary
-
-dictionary
- An associative array, where arbitrary keys are mapped to values. The use of
- :class:`dict` much resembles that for :class:`list`, but the keys can be any
- object with a :meth:`__hash__` function, not just integers starting from zero.
- Called a hash in Perl.
-
- .. index:: single: duck-typing
-
-duck-typing
- Pythonic programming style that determines an object's type by inspection of its
- method or attribute signature rather than by explicit relationship to some type
- object ("If it looks like a duck and quacks like a duck, it must be a duck.")
- By emphasizing interfaces rather than specific types, well-designed code
- improves its flexibility by allowing polymorphic substitution. Duck-typing
- avoids tests using :func:`type` or :func:`isinstance`. Instead, it typically
- employs :func:`hasattr` tests or *EAFP* programming.
-
- .. index:: single: EAFP
-
-EAFP
- Easier to ask for forgiveness than permission. This common Python coding style
- assumes the existence of valid keys or attributes and catches exceptions if the
- assumption proves false. This clean and fast style is characterized by the
- presence of many :keyword:`try` and :keyword:`except` statements. The technique
- contrasts with the *LBYL* style that is common in many other languages such as
- C.
-
- .. index:: single: __future__
-
-__future__
- A pseudo module which programmers can use to enable new language features which
- are not compatible with the current interpreter. For example, the expression
- ``11/4`` currently evaluates to ``2``. If the module in which it is executed had
- enabled *true division* by executing::
-
- from __future__ import division
-
- the expression ``11/4`` would evaluate to ``2.75``. By importing the
- :mod:`__future__` module and evaluating its variables, you can see when a new
- feature was first added to the language and when it will become the default::
-
- >>> import __future__
- >>> __future__.division
- _Feature((2, 2, 0, 'alpha', 2), (3, 0, 0, 'alpha', 0), 8192)
-
- .. index:: single: generator
-
-generator
- A function that returns an iterator. It looks like a normal function except
- that values are returned to the caller using a :keyword:`yield` statement
- instead of a :keyword:`return` statement. Generator functions often contain one
- or more :keyword:`for` or :keyword:`while` loops that :keyword:`yield` elements
- back to the caller. The function execution is stopped at the :keyword:`yield`
- keyword (returning the result) and is resumed there when the next element is
- requested by calling the :meth:`next` method of the returned iterator.
-
- .. index:: single: generator expression
-
-generator expression
- An expression that returns a generator. It looks like a normal expression
- followed by a :keyword:`for` expression defining a loop variable, range, and an
- optional :keyword:`if` expression. The combined expression generates values for
- an enclosing function::
-
- >>> sum(i*i for i in range(10)) # sum of squares 0, 1, 4, ... 81
- 285
-
- .. index:: single: GIL
-
-GIL
- See *global interpreter lock*.
-
- .. index:: single: global interpreter lock
-
-global interpreter lock
- The lock used by Python threads to assure that only one thread can be run at
- a time. This simplifies Python by assuring that no two processes can access
- the same memory at the same time. Locking the entire interpreter makes it
- easier for the interpreter to be multi-threaded, at the expense of some
- parallelism on multi-processor machines. Efforts have been made in the past
- to create a "free-threaded" interpreter (one which locks shared data at a
- much finer granularity), but performance suffered in the common
- single-processor case.
-
- .. index:: single: IDLE
-
-IDLE
- An Integrated Development Environment for Python. IDLE is a basic editor and
- interpreter environment that ships with the standard distribution of Python.
- Good for beginners, it also serves as clear example code for those wanting to
- implement a moderately sophisticated, multi-platform GUI application.
-
- .. index:: single: immutable
-
-immutable
- An object with fixed value. Immutable objects are numbers, strings or tuples
- (and more). Such an object cannot be altered. A new object has to be created
- if a different value has to be stored. They play an important role in places
- where a constant hash value is needed, for example as a key in a dictionary.
-
- .. index:: single: integer division
-
-integer division
- Mathematical division discarding any remainder. For example, the expression
- ``11/4`` currently evaluates to ``2`` in contrast to the ``2.75`` returned by
- float division. Also called *floor division*. When dividing two integers the
- outcome will always be another integer (having the floor function applied to
- it). However, if one of the operands is another numeric type (such as a
- :class:`float`), the result will be coerced (see *coercion*) to a common type.
- For example, an integer divided by a float will result in a float value,
- possibly with a decimal fraction. Integer division can be forced by using the
- ``//`` operator instead of the ``/`` operator. See also *__future__*.
-
- .. index:: single: interactive
-
-interactive
- Python has an interactive interpreter which means that you can try out things
- and immediately see their results. Just launch ``python`` with no arguments
- (possibly by selecting it from your computer's main menu). It is a very powerful
- way to test out new ideas or inspect modules and packages (remember
- ``help(x)``).
-
- .. index:: single: interpreted
-
-interpreted
- Python is an interpreted language, as opposed to a compiled one. This means
- that the source files can be run directly without first creating an executable
- which is then run. Interpreted languages typically have a shorter
- development/debug cycle than compiled ones, though their programs generally also
- run more slowly. See also *interactive*.
-
- .. index:: single: iterable
-
-iterable
- A container object capable of returning its members one at a time. Examples of
- iterables include all sequence types (such as :class:`list`, :class:`str`, and
- :class:`tuple`) and some non-sequence types like :class:`dict` and :class:`file`
- and objects of any classes you define with an :meth:`__iter__` or
- :meth:`__getitem__` method. Iterables can be used in a :keyword:`for` loop and
- in many other places where a sequence is needed (:func:`zip`, :func:`map`, ...).
- When an iterable object is passed as an argument to the builtin function
- :func:`iter`, it returns an iterator for the object. This iterator is good for
- one pass over the set of values. When using iterables, it is usually not
- necessary to call :func:`iter` or deal with iterator objects yourself. The
- ``for`` statement does that automatically for you, creating a temporary unnamed
- variable to hold the iterator for the duration of the loop. See also
- *iterator*, *sequence*, and *generator*.
-
- .. index:: single: iterator
-
-iterator
- An object representing a stream of data. Repeated calls to the iterator's
- :meth:`next` method return successive items in the stream. When no more data is
- available a :exc:`StopIteration` exception is raised instead. At this point,
- the iterator object is exhausted and any further calls to its :meth:`next`
- method just raise :exc:`StopIteration` again. Iterators are required to have an
- :meth:`__iter__` method that returns the iterator object itself so every
- iterator is also iterable and may be used in most places where other iterables
- are accepted. One notable exception is code that attempts multiple iteration
- passes. A container object (such as a :class:`list`) produces a fresh new
- iterator each time you pass it to the :func:`iter` function or use it in a
- :keyword:`for` loop. Attempting this with an iterator will just return the same
- exhausted iterator object used in the previous iteration pass, making it appear
- like an empty container.
-
- .. index:: single: LBYL
-
-LBYL
- Look before you leap. This coding style explicitly tests for pre-conditions
- before making calls or lookups. This style contrasts with the *EAFP* approach
- and is characterized by the presence of many :keyword:`if` statements.
-
- .. index:: single: list comprehension
-
-list comprehension
- A compact way to process all or a subset of elements in a sequence and return a
- list with the results. ``result = ["0x%02x" % x for x in range(256) if x % 2 ==
- 0]`` generates a list of strings containing hex numbers (0x..) that are even and
- in the range from 0 to 255. The :keyword:`if` clause is optional. If omitted,
- all elements in ``range(256)`` are processed.
-
- .. index:: single: mapping
-
-mapping
- A container object (such as :class:`dict`) that supports arbitrary key lookups
- using the special method :meth:`__getitem__`.
-
- .. index:: single: metaclass
-
-metaclass
- The class of a class. Class definitions create a class name, a class
- dictionary, and a list of base classes. The metaclass is responsible for taking
- those three arguments and creating the class. Most object oriented programming
- languages provide a default implementation. What makes Python special is that
- it is possible to create custom metaclasses. Most users never need this tool,
- but when the need arises, metaclasses can provide powerful, elegant solutions.
- They have been used for logging attribute access, adding thread-safety, tracking
- object creation, implementing singletons, and many other tasks.
-
- .. index:: single: mutable
-
-mutable
- Mutable objects can change their value but keep their :func:`id`. See also
- *immutable*.
-
- .. index:: single: namespace
-
-namespace
- The place where a variable is stored. Namespaces are implemented as
- dictionaries. There are the local, global and builtin namespaces as well as
- nested namespaces in objects (in methods). Namespaces support modularity by
- preventing naming conflicts. For instance, the functions
- :func:`__builtin__.open` and :func:`os.open` are distinguished by their
- namespaces. Namespaces also aid readability and maintainability by making it
- clear which module implements a function. For instance, writing
- :func:`random.seed` or :func:`itertools.izip` makes it clear that those
- functions are implemented by the :mod:`random` and :mod:`itertools` modules
- respectively.
-
- .. index:: single: nested scope
-
-nested scope
- The ability to refer to a variable in an enclosing definition. For instance, a
- function defined inside another function can refer to variables in the outer
- function. Note that nested scopes work only for reference and not for
- assignment which will always write to the innermost scope. In contrast, local
- variables both read and write in the innermost scope. Likewise, global
- variables read and write to the global namespace.
-
- .. index:: single: new-style class
-
-new-style class
- Any class that inherits from :class:`object`. This includes all built-in types
- like :class:`list` and :class:`dict`. Only new-style classes can use Python's
- newer, versatile features like :meth:`__slots__`, descriptors, properties,
- :meth:`__getattribute__`, class methods, and static methods.
-
- .. index:: single: Python3000
-
-Python3000
- A mythical python release, not required to be backward compatible, with
- telepathic interface.
-
- .. index:: single: __slots__
-
-__slots__
- A declaration inside a *new-style class* that saves memory by pre-declaring
- space for instance attributes and eliminating instance dictionaries. Though
- popular, the technique is somewhat tricky to get right and is best reserved for
- rare cases where there are large numbers of instances in a memory-critical
- application.
-
- .. index:: single: sequence
-
-sequence
- An *iterable* which supports efficient element access using integer indices via
- the :meth:`__getitem__` and :meth:`__len__` special methods. Some built-in
- sequence types are :class:`list`, :class:`str`, :class:`tuple`, and
- :class:`unicode`. Note that :class:`dict` also supports :meth:`__getitem__` and
- :meth:`__len__`, but is considered a mapping rather than a sequence because the
- lookups use arbitrary *immutable* keys rather than integers.
-
- .. index:: single: Zen of Python
-
-Zen of Python
- Listing of Python design principles and philosophies that are helpful in
- understanding and using the language. The listing can be found by typing
- "``import this``" at the interactive prompt.
