I need a way to get a dictionary value if its key exists, or simply return None
, if it does not.
However, Python raises a KeyError
exception if you search for a key that does not exist. I know that I can check for the key, but I am looking for something more explicit. Is there a way to just return None
if the key does not exist?

You can use dict.get()
value = d.get(key)
which will return None
if key is not in d
. You can also provide a different default value that will be returned instead of None
:
value = d.get(key, "empty")
