Delete a dictionary item if the key exists
python, python-2.7
Solution
You can use `dict.pop`:
mydict.pop("key", None)
Note that if the second argument, i.e. `None` is not given, `KeyError` is raised if the key is not in the dictionary. Providing the second argument prevents the conditional exception.
Problem
Is there any other way to delete an item in a dictionary only if the given key exists, other than: ``` if key in mydict: del mydict[key] ``` The scenario is that I'm given a collection of keys to be removed from a given dictionary, but I am not certain if all of them exist in the dictionary. Just in case I miss a more efficient solution.
