🎯 Learning Objectives

By the end of this lesson, learners will be able to:

  • Use the input() function to receive user input

  • Understand that input() returns a string by default

  • Convert strings to other data types (int, float, bool)

  • Handle basic type conversion errors

📚 Lesson Content

🔹 What is input() in Python?

The input() function lets you get data from the user during program execution.

python
name = input("What is your name? ")
print("Hello", name)

✅ Whatever the user types is always returned as a string, even if it’s a number.

🔸 Type Conversion (Type Casting)

Type conversion means changing the data type of a variable or value.

Python provides built-in functions:

  • int() → Convert to integer

  • float() → Convert to float

  • str() → Convert to string

  • bool() → Convert to boolean

🔄 Converting Input

Example: Get a number from the user and double it

python
user_input = input("Enter a number: ")
number = int(user_input)
print("Double of your number is:", number * 2)

✅ You must convert input if you want to treat it as a number.

💥 Common Mistake

python
age = input("Enter your age: ")
print(age + 5) # ❌ Error: Can't add int to str

✅ Fix:

python
age = int(input("Enter your age: "))
print(age + 5)

🔁 Example: All Data Types with Input

python
name = input("Your name: ") # str
age = int(input("Your age: ")) # int
height = float(input("Your height: ")) # float
is_student = input("Are you a student (yes/no)? ") == "yes" # bool

⚠️ Caution: Input Errors

If you try to convert a non-numeric string to int or float, it will raise a ValueError.

python
num = int("abc") # ❌ ValueError

🛠️ We’ll learn error handling later!

📝 Assignment

Create a small script that:

  1. Asks the user for their name, age, and weight

  2. Converts age to int and weight to float

  3. Prints a summary like:
    "Hello Alice, you are 24 years old and weigh 55.5 kg."
