Python Type Function

🧐 Why It Matters

Every value in Python has a type — integer, string, list, etc. The type() function helps you check what type a value is. It’s simple but powerful — a real Python supertool 🛠️.

✍️ Syntax

type(object)

It returns something like:

<class 'int'>
<class 'str'>

🔍 Example

x = 10
print(type(x))  # Output: <class 'int'>

No guesswork — you instantly know what you’re dealing with.

🔢 Common Data Types

  • int – Whole numbers (5, -3)
  • float – Decimals (3.14, -0.5)
  • str – Text ("Hello")
  • list – Items in brackets ([1, 2, 3])
  • tuple – Like lists but unchangeable ((1, 2))
  • dict – Key-value pairs ({"name": "Ken"})
  • bool – True or False

⚠️ Why You Should Care

Knowing types avoids errors like:

"5" + 5  # ❌ TypeError!

Instead:

int("5") + 5  # ✅ 10

The type() function helps you debug, build smarter logic, and write cleaner code.
