5. Miscellaneous Services

The modules described in this chapter provide miscellaneous services that are available in all Python versions. Here's an overview:

math Mathematical functions (sin() etc.).

cmath Mathematical functions for complex numbers.

random Generate pseudo-random numbers with various common distributions.

whrandom Floating point pseudo-random number generator.

bisect Array bisection algorithms for binary searching.

array Efficient arrays of uniformly typed numeric values.

ConfigParser Configuration file parser.

fileinput Perl-like iteration over lines from multiple input streams, with ``save in place'' capability.

calendar General functions for working with the calendar, including some emulation of the Unix<#12672#><#12672#> cal program.

cmd Build line-oriented command interpreters; this is used by module pdb.

shlex Simple lexical analysis for Unix<#12955#><#12955#> shell-like languages.
