Python Keywords: Complete List with Examples

✍️ Introduction

In Python programming, keywords are reserved words that have a special meaning.

These words are used to define the structure and logic of a Python program.

👉 Keywords cannot be used as variable names, function names, or identifiers.

What are Python Keywords?

Python keywords are predefined words that are already stored in Python.

Each keyword performs a specific function in the program.

Example:

if, else, for, while

🔢 Total Number of Python Keywords

Python currently has 35 keywords (may change in future versions).

🧑‍💻 Examples of Python Keywords

Example 1: Using if keyword

Correct:

if_value = 10

📝 How to Check Python Keywords?

You can check all keywords using:

import keyword

print(keyword.kwlist)
