Lambda forms (lambda expressions) have the same syntactic position as
expressions. They are a shorthand to create anonymous functions; the
expression \code{lambda \var{arguments}: \var{expression}}

-\strong{Programmer's note:} Prior to Python 2.1, a lambda form defined
-inside a function has no access to names defined in the function's
-namespace. This is because Python had only two scopes: local and
-global. A common work-around was to use default argument values to
-pass selected variables into the lambda's namespace, e.g.:
-
-\begin{verbatim}
-def make_incrementor(increment):
- return lambda x, n=increment: x+n
-\end{verbatim}
-
-As of Python 2.1, nested scopes were introduced, and this work-around
-has not been necessary. Python 2.1 supports nested scopes in modules
-which include the statement \samp{from __future__ import
-nested_scopes}, and more recent versions of Python enable nested
-scopes by default. This version works starting with Python 2.1:
-
-\begin{verbatim}
-from __future__ import nested_scopes
-
-def make_incrementor(increment):
- return lambda x: x+increment
