You can use the following syntax to delete the element from Dictionary: del d[key] The above code mutates the existing dictionary but if you want to return a new dictionary, make a copy of the dictionary using the following code: def removekey(d, key): r = dict(d) del r[key] return r If you want to learn handling dictionaries then check out this Python Tutorial by Intellipaat.
