Convert List items as keys in dictionary with enumerated value By using enumerate(), we can convert a list into a dictionary with index as key and list item as the value. If no default value was passed in fromKeys() then default value for keys in dictionary will be None. The Clear() method deletes all the elements of the dictionary. Convert Multiple Lists to Dictionary in Python (3 Examples) 1) Create Sample Lists 2) Example 1: Transform the Lists into a Dictionary with dict() & zip(). All dictionary items will have same value, that was passed in fromkeys(). The Remove() method deletes an existing key-value pair from a dictionary. It returns a dictionary with items in list as keys.

We also discovered the basics of lists and dictionaries in Python. All of them modify the original dictionary in place. copy () on EVERY dict and list you want to copy, even those in your dict/list. The generator expression iterates over key-value pairs in the original dictionary. copy () onto your list, else it would be a link of your dict and not a new dict with the same values. We have seen three ways of doing this operation: using the append () and update () methods and also, using the + operator. Use the dict () constructor with a generator expression to update the dictionary. What is Dictionary Comprehension in Python? In this article, we have learned how to append new elements to an existing list in a Python dictionary. ![]()
