List and Tuple

Explore the fundamentals of Python lists and tuples in this lesson. Learn how to create, modify, and manipulate lists using methods like append, insert, remove, and more. Understand the difference in mutability between lists and tuples, and when to use each. This knowledge helps you work effectively with Python containers necessary for data science tasks.

We'll cover the following...

Lists

Lists are containers that are used to store multiple data elements. Lists have an order of elements and have a count of elements. These ordered elements can be accessed by the index. The index order starts from 0 and goes the length of the list.

Python 3.5
pcodes = ['SC1','SF5','BH3']
print(pcodes)
print(type(pcodes))

The above code creates a list of three elements. The list’s object class is list. We can get ...
