Today I was in need of comparing two Python dictionaries with each other — including nested dictionaries. In Python 3, the zip () method now returns a lazy iterator, which is now the most used approach. Whenever we talk about storing data in the form of key-value pair in python, the data structure that comes first into mind is a python dictionary.If you come from a JAVA background, you must be familiar with hash maps and hash tables. Python Dictionary basically contains elements in the form of key-value pairs. Initialize an empty dictionary. But either way, it creates an empty dict and then checks whether the key exists before returning the actual value. Python is a lovely language for data processing, but it can get a little verbose when dealing with large nested dictionaries.

What you now deal with is a "key-value" pair, which is sometimes a more appropriate data structure for many problem instead of a simple list. I found myself needed zip but for dictionaries, and wanted to know if there is any way I can make this shorter and more concise, and/or faster. Like dictionaries, it has keys and values.
