🧮 Let’s Learn About Numbers in Python!
Hi young coder! 👋 Today, we’re going to learn how Python (a computer language) understands numbers. Yes, Python is smart, and it knows how to work with different kinds of numbers!
Let’s go! 🚀
🔢 1. Integer Numbers – Whole Numbers
These are numbers like 1, 5, 100, or even 0. No dots, no fractions!
🧠 In Python:
age = 8
or
age = int(8)
Want to check if age is an integer?
type(age) == int # This will say True!
✅ int means “integer.”
🌊 2. Floating Point Numbers – Numbers with a Dot
These are numbers like 0.1, 3.14, or 100.0. They’re also called floats in Python.
🧠 In Python:
fraction = 0.1
or
fraction = float(0.1)
To check if it’s a float:
type(fraction) == float # True!
✅ float means it has a decimal point.
🧙♂️ 3. Complex Numbers – Real + Magical
These are special numbers with two parts:
- A real part (normal)
- An imaginary part (with a little magic
j!)
🧠 In Python:
complexNumber = 2 + 3j
or
complexNumber = complex(2, 3)
You can even ask Python to tell you the parts:
complexNumber.real # This gives 2.0 (real part)
complexNumber.imag # This gives 3.0 (imaginary part)
To check if it’s complex:
type(complexNumber) == complex # True!
✅ complex means it’s made of two parts — real and imaginary!
🎯 Quick Recap!
| Type | Example | Type Name in Python |
|---|---|---|
| Whole Number | 8 |
int |
| Fraction | 0.5 |
float |
| Real + Imaginary | 2 + 3j |
complex |
🎮 Try This Challenge!
Type these in your Python editor and see what happens:
print(type(5))
print(type(3.14))
print(type(2 + 4j))
Can you guess what Python will say? 😄
That’s it for today, little coder! Next time, we’ll use these numbers to make cool programs! 💻🧠
