How to remove a key from a Python dictionary?

Question

When trying to delete a key from a dictionary, I write: if 'key' in myDict: del myDict['key']Is there a one line way of doing this?

Answer 1

If you use `defaultdict`, it'll already have the mapping initialized, so you don't need to perform the key check.

from collections import defaultdict

d = defaultdict(str)

d['key'] = 1

d.pop('key') # the "one liner"
