Why 5 + 3 = 53 in Python (And How to Fix It)
Why does Python think 5 + 3 is 53? In this video, we dissect how Python handles user input and build an interactive calculator using type casting.
You'll learn how to turn text input into whole integers and decimal floats so you can perform actual calculations in your code instead of gluing text together.
📝 CODE WRITTEN IN THIS VIDEO:
--------------------------------------
Converting to whole numbers (integers)
num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))
print(num1 + num2)
Converting to decimal values (floats)
num1 = float(input("Enter first number: "))
