How to generate all possible strings in python?

Question

My goal is to be able to generate all possible strings (Letters and numbers) of length x and be able to activate a block of code for each one. (like an iterator) The only pr

Answer 1

Use itertools.product():

>>> import itertools
>>> map(''.join, itertools.product('ABC', repeat=3))
['AAA', 'AAB', 'AAC', 'ABA', 'ABB', 'ABC', 'ACA', 'ACB', 'ACC', 'BAA', 'BAB', 'BAC', 'BBA', 'BBB', 'BBC', 'BCA', 'BCB', 'BCC', 'CAA', 'CAB', 'CAC', 'CBA', 'CBB', 'CBC', 'CCA', 'CCB', 'CCC']

Note that creating a list containing all combinations is very inefficient for longer strings - iterate over them instead:

for string in itertools.imap(''.join, itertools.product('ABC', repeat=3)):
    print string

To get all characters and numbers use string.uppercase + string.lowercase + string.digits.
