pair: octal; literals
Numbers are created by numeric literals or as the result of built-in functions
-and operators. Unadorned integer literals (including hex and octal numbers)
-yield plain integers unless the value they denote is too large to be represented
-as a plain integer, in which case they yield a long integer. Integer literals
-with an ``'L'`` or ``'l'`` suffix yield long integers (``'L'`` is preferred
-because ``1l`` looks too much like eleven!). Numeric literals containing a
-decimal point or an exponent sign yield floating point numbers. Appending
-``'j'`` or ``'J'`` to a numeric literal yields a complex number with a zero real
-part. A complex numeric literal is the sum of a real and an imaginary part.
