title: How to generate all possible strings in python?
body: <p>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 problem is the ones in the itertools don't make copies of the letter in the same string. For example:</p>
  
  <p>I get "ABC"  "BAC" "CAB" etc. instead of "AAA".</p>
  
  <p>Any suggestions?</p>
