The Error That Breaks GCSE Python (Input, Data Types & Calculation)

Learn how to fix TypeErrors in Python by understanding input, data types, and type conversion. This GCSE Computer Science lesson shows why user input starts as a string and how to make calculations work properly. FREE STUDENT WORKSHEET https://docs.google.com/document/d/1y... This is where many students lose marks — not because the maths is wrong, but because the data type is. In this video, you’ll learn how Python handles user input, why input() always returns text (a string), and how to convert values using int() and float() so your programs calculate correctly. In this lesson you will: • Understand why input() returns a string • Identify and fix TypeErrors • Convert data types correctly • Write working calculation programs • Apply input and calculations in a GCSE-style example Perfect for: • GCSE Computer Science (AQA 8525) • Students learning Python from scratch • Teachers delivering programming lessons 📘 Full GCSE Python playlist:    • GCSE Python: Full Beginner Programming Course   🔔 Subscribe for structured, exam-ready Computer Science lessons 📥 Free worksheets and classroom-ready resources coming soon! This lesson is built for: GCSE Computer Science teachers (cover work, homework, in-class) Students learning Python from scratch Anyone who keeps getting errors like: “can’t add str and int” ✅ In this lesson you’ll master input() and how user input is stored The 3 key data types you’ll use constantly: str, int, float Type conversion: int() and float() (casting) Calculations using + - * / Common mistakes that lose marks in exams ⏸️ Pause + Predict (high-impact exam habit) Before running each example: Predict the output Run it Explain what data type caused that result 🧪 Practice Code - alternative to video age = input("Enter your age: ") print(age + 1) ⏸️ Pause: What happens? Why? age = int(input("Enter your age: ")) print(age + 1) price = float(input("Enter price: ")) print("Price with VAT:", price * 1.2) ⭐ Main Mini-Program (extendable calculator) print("Mini Calculator") a = float(input("Enter first number: ")) b = float(input("Enter second number: ")) print("Add:", a + b) print("Subtract:", a - b) print("Multiply:", a * b) if b != 0: print("Divide:", a / b) else: print("Cannot divide by zero") ⏸️ Pause: Change the numbers. Predict each output. Run it. Try decimals. Try b = 0. Explain what changes. 🎯 GCSE Exam Tip Most calculation mistakes happen because: input() produces a string You must convert to int or float before maths Indentation hasn't happened because of a missing colon ▶️ Next lesson Lesson 5 – Selection (IF): Making decisions in code #python #gcse #computerscience #coding #datatypes #typeconversion #teacherresources #learnpython #learntocode #programming
