python .findall

## Search for pattern 'bb' in string 'aabbcc'.
  ## All of the pattern must match, but it may appear anywhere.
  ## On success, match.group() is matched text.
  match = re.search(r'bb', 'aabbcc') # found, match.group() == "bb"
  match = re.search(r'cd', 'aabbcc') # not found, match == None

  ## . = any char but n
  match = re.search(r'...c', 'aabbcc') # found, match.group() == "abbc"

  ## d = digit char, w = word char
  match = re.search(r'ddd', 'p123g') # found, match.group() == "123"
  match = re.search(r'www', '@@abcd!!') # found, match.group() == "abc"
