Python Syntax

Python syntax means the basic rules used to write Python code. The syntax is simple, which makes Python easy for beginners to learn.

Basic Example

print("Hello, World!")

This code prints:

Hello, World!

Indentation

Python uses spaces to show which code belongs to a particular block.

if age >= 18:
    print("You are an adult")

The spaces before print() are important. Incorrect indentation can cause an error.

Variables

Variables are used to store values.

name = "Vishnu"
age = 21

print(name)
print(age)

Comments

Comments are used to explain code. They start with #.

# This is a comment
print("Hello")

Python ignores comments when running the program.

Case Sensitive

Python treats uppercase and lowercase letters differently.

name = "Vishnu"
Name = "Rahul"

Here, name and Name are two different variables.

Colon :

A colon is used before a block of code, such as with if, for, while, functions, and classes.

if age >= 18:
    print("Eligible")
