import re
def urlify(s):
# Remove all non-word characters (everything except numbers and letters)
s = re.sub(r"[^\w\s]", '', s)
# Replace all runs of whitespace with a single dash
s = re.sub(r"\s+", '-', s)
return s
# Prints: I-cant-get-no-satisfaction"
print(urlify("I can't get no satisfaction!"))
