Lists in Python Practical Part 3 | remove(), pop(), clear(), len(), count(), index() | Lesson 21

🚀 Welcome to Complete Python Mastery – Lesson 21 | Lists in Python – Practical Part 3! In this practical session, we continue working with Python Lists through hands-on coding examples in VS Code. In Practical Part 1, we learned how to create Lists, access items using Positive & Negative Indexing, and work with List Slicing. In Practical Part 2, we learned how to update List items and add new items using append(), insert(), and extend(). Now, in Practical Part 3, we will learn how to REMOVE items from a List and use some very useful List tools — step by step with practical Python code. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📚 TOPICS COVERED IN THIS VIDEO 🔹 REMOVING ITEMS FROM A LIST ✅ remove() Method • Remove an item using its value • Understand what happens with duplicate values • Understand ValueError when the value does not exist ✅ pop() Method • Remove an item using its index • Use pop() without an index to remove the last item • Understand how pop() returns the removed item ✅ clear() Method • Remove all items from a List • Understand that clear() makes the List empty but does not delete the List itself 🔹 USEFUL LIST TOOLS ✅ len() • Find the total number of items in a List • Understand List Length vs Last Index • Understand why a List with length 4 has the last positive index 3 ✅ count() • Find how many times a particular value appears in a List • Understand what count() returns when a value is not present ✅ index() • Find the index position of a particular value • Understand how index() works with duplicate values • Understand what happens when a value is not found 💡 IMPORTANT CONCEPT: len() is a built-in Python function. count() and index() are List methods. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📝 PRACTICE QUESTIONS — TRY IT YOURSELF! After watching the complete lesson, try solving these questions yourself in VS Code. 💻 QUESTION 1 — remove() Given List: fruits = ["Apple", "Mango", "Banana", "Orange"] Task: Use the remove() method to remove "Banana" from the List and print the updated List. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💻 QUESTION 2 — len() & count() Given List: numbers = [10, 20, 10, 30, 10, 40] Tasks: 1. Use len() to find the total number of items in the List. 2. Use count() to find how many times the value 10 appears in the List. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💻 QUESTION 3 — index() & pop() Given List: students = ["Ali", "Ahmed", "Sara", "Zoya"] Tasks: 1. Use the index() method to find the index position of "Sara". 2. Use pop() to remove the item at that same index position. 3. Print the final updated List. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎯 PRACTICE TIP: Do not just watch the code! Open VS Code and type every program yourself. Try to understand: remove() → Removes by VALUE pop() → Removes by INDEX pop() without index → Removes the LAST ITEM clear() → Removes ALL ITEMS len() → How many total items? count() → How many times does a value appear? index() → At which position is the value? Try solving all 3 practice questions without looking back at the examples.
