String modules useful constants

Python’s string module provides constants for string related operations. To use them, import the string module:

>>> import string

string.ascii_letters:

Concatenation of ascii_lowercase and ascii_uppercase:

>>> string.ascii_letters
'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'

string.ascii_lowercase:

Contains all lower case ASCII characters:

>>> string.ascii_lowercase
'abcdefghijklmnopqrstuvwxyz'

string.ascii_uppercase:

Contains all upper case ASCII characters:

>>> string.ascii_uppercase
'ABCDEFGHIJKLMNOPQRSTUVWXYZ'

string.digits:

Contains all decimal digit characters:

>>> string.digits
'0123456789'

string.hexdigits:

Contains all hex digit characters:

>>> string.hexdigits
'0123456789abcdefABCDEF'

string.octaldigits:

Contains all octal digit characters:

>>> string.octaldigits
'01234567'

string.punctuation:

Contains all characters which are considered punctuation in the C locale:

>>> string.punctuation
'!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~'

string.whitespace:

Contains all ASCII characters considered whitespace:

>>> string.whitespace
' \t\n\r\x0b\x0c'

In script mode, print(string.whitespace) will print the actual characters, use str to get the string returned above.

string.printable:

Contains all characters which are considered printable; a combination of string.digits, string.ascii_letters, string.punctuation, and string.whitespace.

>>> string.printable
'0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~ \t\n\r\x0b\x0c'
