Is there more elegant way for this type of permutations?

Question

I have this code:

import itertools
variations = list(itertools.permutations(['a', 'b', 'c'], 2))
for v in variations:
    print(''.join(v))

I want all characters. If I want use this code I should write something like this:

variations = list(itertools.permutations(['a', 'b', 'c', 'd', 'e', '.......

Isn't there a more elegant way?

Answer 1

You can just use a string instead of a list of strings. Additionally, you can use the string module and use the predefined constant ascii_lowercase for all lowercase letters:

import string
variations = itertools.permutations(string.ascii_lowercase, 2)

If you want additional characters you can just grow the string to include the characters you want or you can use one of the other string constants defined in the string module:

...permutations(string.ascii_lowercase + '/\\$!@#%', 2)
...permutations(string.printable, 2)
