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

Dictionary data type has a method called dict_name.pop(item) and this can be used to delete a key:value pair from a dictionary.

a={9:4,2:3,4:2,1:3}
a.pop(9)
print(a)

This will give the output as:

{2: 3, 4: 2, 1: 3}

This way you can delete an item from a dictionary in one line.
