Lists in Python

Course Overview

This course offers a detailed exploration of Python lists, from the basic syntax to advanced list operations. You’ll learn about various list methods, how to manipulate data efficiently, and practical applications that you can use in real-world scenarios.

What You Will Learn

  • Python Lists: Introduction: Understand what lists are, why they are important, and how they fit into the broader landscape of Python data structures.
  • List Methods: Learn about the wide array of built-in methods that Python offers for working with lists, such as:
    • append(): Add an element to the end of a list.
    • clear(): Delete all entries in the list.
    • copy(): Create a copy of the list.
    • count(): Return the number of times a specific element appears in the list.
    • extend(): Add all elements from one list to another.
    • index(): Search for an element and return its index.
    • insert(): Insert an element at a specific position.
    • pop(): Remove an element by index and return it.
    • remove(): Remove the first occurrence of an element by value.
    • sort(): Sort the list in ascending or descending order.

Hands-On Code Examples

To solidify your understanding and give you practical experience, this course includes a variety of code examples:

  • Length of a List: Learn how to find the number of items in a list using the len() function.
  • Smallest and Largest Number in a List: Write a function that finds the smallest and largest numbers in a given list.
  • Arithmetic Functions on Lists: Perform arithmetic operations on entire lists, such as summing elements or calculating the average.
  • Even Numbers in a List: Create a function that filters out only the even numbers from a list.
  • Odd Numbers in a List: Similarly, learn how to filter out odd numbers from a list.
  • Print Indices of All Pairs: Write a function that prints the indices of all pairs of numbers that meet a specific condition.
  • Join Two Lists: Combine two lists into one using Python’s built-in methods.
  • List in Reverse Order: Reverse the order of elements in a list efficiently.
  • Find Pairs with Target Sum: Implement a function to find pairs of numbers in a list that sum to a specific target.
