How to remove a key from a Python dictionary?

Question

When deleting a key from a dictionary, I use:

if \'key\' in my_dict:
    del my_dict[\'key\']

Is there a one line way of doing this?

Answer 1

It took me some time to figure out what exactly my_dict.pop("key", None) is doing. So I'll add this as an answer to save others Googling time:

pop(key[, default])

If key is in the dictionary, remove it and return its value, else return default. If default is not given and key is not in the dictionary, a KeyError is raised.
