Python Lists & Arrays Explained | List Methods + array Module Tutorial for Beginners
Master Python Lists and Python Arrays in this beginner-friendly hands-on tutorial. In this video, you will learn the most commonly used Python list methods and understand how Python arrays work using the built-in array module.
Python lists are one of the most important data structures in Python. They are flexible, ordered, mutable, and widely used in real-world programming. We will cover practical list methods like append(), extend(), insert(), remove(), pop(), sort(), reverse(), copy(), index(), and count() with easy coding examples.
You will also learn Python arrays using the built-in array module. We will compare Python lists vs arrays and understand when to use lists for general-purpose programming and when to use arrays for memory-efficient numeric storage.
This tutorial is perfect for Python beginners, coding interview preparation, data engineering learners, and anyone who wants to build strong Python fundamentals.

Example Concepts Covered
Python List:
nums = [10, 20, 30]
nums.append(40)
print(nums)
Python Array:
import array as arr
nums = arr.array('i', [10, 20, 30])
print(nums)
Key Takeaway
Use Python lists for general-purpose programming when you need flexibility. Use Python arrays when you are working with same-type numeric data and memory efficiency matters.
