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

You can use a dictionary comprehension to create a new dictionary with that key removed:

>>> my_dict = {k: v for k, v in my_dict.items() if k != 'key'}

You can delete by conditions. No error if key doesn't exist.
