# Warning: most of the code you see here isn't normally used nowadays.  With
# Python 1.6, many of these functions are implemented as methods on the
# standard string object. They used to be implemented by a built-in module
# called strop, but strop is now obsolete itself.

"""Common string manipulations.

Public module variables:

whitespace -- a string containing all characters considered whitespace
lowercase -- a string containing all characters considered lowercase letters
uppercase -- a string containing all characters considered uppercase letters
letters -- a string containing all characters considered letters
digits -- a string containing all characters considered decimal digits
hexdigits -- a string containing all characters considered hexadecimal digits
octdigits -- a string containing all characters considered octal digits
