Sometimes it takes longer to figure out the regex than to just write it out in python   import string s    how much for the maple syrup   20 99  That s ricidulous     for char in string punctuation      s   s replace char         If you need other characters you can change it to use a white-list or extend your black-list   Sample white-list   whitelist   string letters   string digits       new s      for char in s      if char in whitelist          new s    char     else          new s          Sample white-list using a generator-expression   whitelist   string letters   string digits       new s      join c for c in s if c in whitelist

I often just open the console and look for the solution in the objects methods  Quite often it s already there    gt  gt  gt  a    hello   s   gt  gt  gt  dir a            partition    replace           gt  gt  gt  a replace            hello   s    Short answer  Use string replace
