Welcome to the basics of Python! Python is a versatile programming language that is widely used for web development, data analysis, and automation. In this section, we will cover the fundamental concepts of Python programming.

Installation

Before you start coding in Python, you need to install the Python interpreter. You can download it from the official Python website: Python Installer.

Hello World

The first program in Python is the "Hello World" program. It's a simple program that prints "Hello, World!" to the console.

print("Hello, World!")

Variables

In Python, variables are used to store data values. Variables are defined by a name and can be assigned a value.

x = 5
y = "Hello"

Data Types

Python has several built-in data types:

  • Numbers: Integers, floating-point numbers, and complex numbers.
  • Strings: A sequence of characters.
  • Booleans: True or False values.

Control Structures

Python uses control structures to control the flow of execution.

  • If-Else: Conditional statements.
  • For-Loop: Iterates over a sequence.
  • While-Loop: Executes a block of code as long as a condition is true.

Functions

Functions are blocks of reusable code that perform a single, related action.

def greet(name):
    print(f"Hello, {name}!")

greet("Alice")

Modules

Python modules are files containing Python code. They can be imported into other Python scripts.

import math

print(math.sqrt(16))
