RandCharGen
Updated March 14, 2019 to use Python 3 and the Python 3.6 secrets module
Creates a set of random characters. Can be used as a password generator, a salt generator or create a GAE (Google App Engine) site name generator. Two functions, each returns a random set of characters. One is written in a clearer polyglot way and the other is written in a more Pythonic way. String constants can be changed out to change your random set of characters.
7.1.1. String constants from Python Documentation (http://docs.python.org/2/library/string.html)
The constants defined in this module are:
string.ascii_letters
The concatenation of the ascii_lowercase and ascii_uppercase constants described below. This value is not locale-dependent.
string.ascii_lowercase
The lowercase letters 'abcdefghijklmnopqrstuvwxyz'. This value is not locale-dependent and will not change.
string.ascii_uppercase
The uppercase letters 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'. This value is not locale-dependent and will not change.
string.digits
The string '0123456789'.
string.hexdigits
The string '0123456789abcdefABCDEF'.
string.letters
The concatenation of the strings lowercase and uppercase described below. The specific value is locale-dependent, and will be updated when locale.setlocale() is called.
string.lowercase
A string containing all the characters that are considered lowercase letters. On most systems this is the string 'abcdefghijklmnopqrstuvwxyz'. The specific value is locale-dependent, and will be updated when locale.setlocale() is called.
string.octdigits
The string '01234567'.
string.punctuation
String of ASCII characters which are considered punctuation characters in the C locale.
string.printable
String of characters which are considered printable. This is a combination of digits, letters, punctuation, and whitespace.
string.uppercase
A string containing all the characters that are considered uppercase letters. On most systems this is the string 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'. The specific value is locale-dependent, and will be updated when locale.setlocale() is called.
string.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.
