get(key[, default])

Return the value for key if key is in the dictionary, else default. If default is not given, it defaults to None, so that this method never raises a KeyError.ex:-

dictionary = {"Name": "Harry", "Age": 17} dictionary["Name"] dictionary.get("Name")
It allows you to provide a default value if the key is missing:

dictionary.get("bogus", default_value)

returns default_value (whatever you choose it to be), whereas

dictionary["bogus"]

would raise a KeyError.

If omitted, default_value is None, such that

dictionary.get("bogus") # <-- No default specified -- defaults to None

returns None just like

dictionary.get("bogus", None)

would.
