/python does not work!

When I use `curl cheat.sh/python/filter`
The output is shown below, it does not have any instances, what should I do to get some use cases of this function in cheat.sh?
And I think some contents are outdated already

# rewriting the code so it doesn’t need a list at all. Particularly

# correct transformation is to use a regular `for` loop (since creating
# a list would just be wasteful).
