"WebList. Lists are one of the simple and most commonly used data structures provided in python. It can store multiple data types at the same time like string, int, boolean, etc, and hence it is called heterogeneous. Lists are mutable which means the data inside the list can be altered. Lists contain ordered data and can also contain duplicate values. " - Pop time complexity python
