Python del if in dictionary in one line

Question

Is there a one line way of doing the below?

myDict = {}
if 'key' in myDic:
    del myDic['key']

thanks

Answer 1

You can write

myDict.pop(key, None)

Answer 2

Besides the pop method one can always explictly call the __delitem__ method - which does the same as del, but is done as expression rather than as an statement. Since it is an expression, it can be combined with the inline "if" (Python's version of the C ternary operator):

d = {1:2}

d.__delitem__(1) if 1 in d else None

Answer 3

Would you call this a one liner:

>>> d={1:2}
>>> if 1 in d: del d[1]
... 
>>> d
{}
