Basic Syntax

Python syntax is relatively straightforward and uses indentation to define code blocks. Here's a simple example of a Python script that prints “Hello, World!”:

print(“Hello, World!”)

Variables

Variables are used to store data in Python. You can think of variables as containers that hold values. Unlike some other programming languages, Python is dynamically typed, meaning you don't need to declare the data type of a variable before assigning a value to it.

Variable Naming Rules

- Variable names can contain letters, numbers, and underscores. - Variable names must start with a letter or an underscore. - Variable names are case-sensitive. - Variable names cannot be reserved keywords like `print`, `if`, `else`, etc.

Examples of Variables

String Variables

name = “Alice”

Integer Variables

age = 25

Float Variables

height = 5.9

Boolean Variables

is_student = True

Multiple Assignments

You can also assign multiple variables in a single line:

a, b, c = 1, 2, 3

Comments

Comments are used to explain your code and are ignored by the Python interpreter. You can use comments to make your code more readable.

# This is a comment

Conclusion
