module string: Common String Operations
This module defines some constants that
can check character classes, and some useful string functions. See
the module re
for string functions based on
regular expressions. The constants defined in this module are:
-
digits
The string '
0123456789
‘.-
hexdigits
The string
'0123456789abcdefABCDEF'
.-
letters
The concatenation of the strings
lowercase()
anduppercase()
(check their entries in this list).-
lowercase
A string containing all characters considered lowercase letters. On most systems this is the string
'abcdefghijklmnopqrstuvwxyz'
. Don’t change its definition: the effect on the routinesupper()
andswapcase()
is undefined.-
octdigits
The string
'01234567'
.-
uppercase
A string containing all characters considered uppercase letters. On most systems this is the string
'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
. Don’t change its definition: the effect on the routineslower()
andswapcase()
is undefined.-
whitespace
A string containing all characters that are considered whitespace. On most systems this includes the characters space, tab, linefeed, return, formfeed, and vertical tab. Don’t change its definition: the effect on the routines
strip()
andsplit()
is undefined.
The functions defined in this module are:
-
atof(
s
)
Converts a string to a floating-point number. The string must have the standard syntax for a floating-point literal in Python, optionally preceded by a sign (+ or -). Note that this behaves identically to the built-in function
float()
when passed ...
