Task 21
Clean the text
Models and keyword matchers both do better on clean text: lower case, no stray spaces, no punctuation. Normalise first, compare second.
Task
Why lower-case the question first?
The editor already contains a starting point. Change it until every check passes — the Next task button unlocks when it does.
What you start with
raw = ' What is the PYTHON fee?? '
def clean(text):
text = text.strip().lower()
for mark in '?!.,':
text = text.replace(mark, '')
return ' '.join(text.split())
print(clean(raw))
