List iteration returns only last value

P: 1
Hey guys. I am working on a pretty special program here IMO. But i keep encountering one problem. I am trying to append items from one word list to another(filtration reasons). But when the program runs, the list in the end only has the last value from the other list, whereas i know for a fact that there are more values. I am only filtering alphabets out of number.

Here is my code:

Expand|Select|Wrap|Line Numbers
  1. def cleanlist(wordlist):
  2.     for word in wordlist:
  3.         lex = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ "
  4.         for i in range(0,len(lex)):
  5.             word = word.replace(lex[i], "")
  6.             if len(word) > 0:
  7.                 clean_list = []
  8.                 clean_list.append(word)
  9.         print(clean_list)
  10.     f.write(str(clean_list))
  11.

A new, empty list is created each time, so only contains that one entry. See the next line under the "if len(word) > 0:" line. Also, use "".join() to cast a list into a string.
