Installing Python

To start coding in Python, you need to install it on your computer. You can download the latest version of Python from the official Python website. Follow the installation instructions for your operating system, and you're ready to go.

Writing Your First Python Program

Let's dive right into writing a simple Python program. Open your preferred code editor or Python's built-in IDLE and type the following code:

print("Hello, World!")

Save the file with a .py extension and run it. You should see Hello, World! printed on your screen. Congratulations, you've just written your first Python program!

Basic Python Concepts

Here are a few fundamental concepts to get you started:

Variables: Used to store data. Example:

    name = "John"
    age = 25

Data Types: Python supports various data types like integers, floats, strings, lists, and dictionaries.

    age = 25               # Integer
    height = 5.9           # Float
    name = "John"          # String
    friends = ["Alice", "Bob", "Eve"]  # List
    person = {"name": "John", "age": 25}  # Dictionary

Control Structures: Python uses if-else statements and loops to control the flow of the program.

    if age > 18:
        print("You are an adult")
    else:
        print("You are a minor")

    for friend in friends:
        print(friend)

Functions: Blocks of reusable code that perform a specific task.

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

    greet("Alice")
