Introduction to Python

Python is a high-level, interpreted programming language known for its simplicity and readability. It is widely used for web development, data analysis, artificial intelligence, and many other applications. Python's syntax is designed to be intuitive, making it easy for beginners to learn and for experienced programmers to read and write.

Setting Up Python

Before you can start coding in Python, you need to install the Python interpreter on your computer. You can download the latest version of Python from the official website: Python.org.

Basic Syntax

Python uses indentation to define the scope of code blocks. This is different from languages like Java or C, which use curly braces {}. Here's a simple example of Python syntax:

print("Hello, World!")

Variables and Data Types

In Python, variables are used to store data. Python is dynamically typed, which means you don't need to declare the type of a variable when you create it. Here are some common data types:

  • int: Integer
  • float: Floating-point number
  • str: String
  • bool: Boolean
age = 25
name = "Alice"
height = 5.9
is_student = True

Control Flow

Python uses if statements to control the flow of execution based on conditions. Here's an example:

if age > 18:
    print("You are an adult.")
else:
    print("You are not an adult.")

Functions

Functions are blocks of code that perform a specific task. They can be reused to simplify your code. Here's an example of a function that calculates the square of a number:

def square(number):
    return number * number

result = square(5)
print(result)
