Python: Remove Non-printable characters from string

Current post is on how to remove non-printable characters from string.

Need a function to remove non-printable characters in python.

Remove Non-printable function for ASCII String:

def    remove_ascii_non_printable(str)
      """Removes Non-printable chars from ASCII String"""
      return ''.join([ch for ch in str if ord(ch) > 31 and ord(ch) < 126 or ord(c) = = 9])

Remove Non-printable function for Unicode String:

def    remove_unicode_non_printable(str)
      """Removes Non-printable chars from ASCII String"""
      return ''.join([ch for ch in str if ord(ch) > 31 or ord(c) = = 9])
