How to Remove Keys From a Dictionary in Python
Python is an easy-to-read, open-source programming language often introduced as a first language for beginning programmers. A dictionary in Python is a datatype that defines one-to-one relationships between keys and values. If you remove the key from a Python dictionary, you will also remove the key's related value. You use the built-in "del" command to delete a key from a dictionary.
