Python is a high-level, interpreted, and general-purpose programming language. It was created by Guido van Rossum and first released in 1991. Python emphasizes code readability and simplicity, making it an excellent language for beginners and experienced developers. Getting Started with Python is easy due to its straightforward syntax and extensive documentation, which provides ample resources for learning and development.

Python Features

  1. Simple and Easy to Learn: Python has a simple syntax, which makes it easy to learn and read. It’s a great language for beginners who are new to programming.
  2. Interpreted: Python is an interpreted language, which means that the Python code is executed line by line. This makes it easy to test and debug code.
  3. High-Level: Python is a high-level language, which means that it abstracts away low-level details like memory management and hardware interaction. This makes it easier to write and understand code.
  4. Dynamic Typing: Python is dynamically typed, which means that you don’t need to declare the data type of a variable explicitly. Python will automatically infer the data type based on the value assigned to the variable.
  5. Strong Typing: Python is strongly typed, which means that the data type of a variable is enforced at runtime. This helps prevent errors and makes the code more robust.
  6. Extensive Standard Library: Python comes with a large standard library that provides tools and modules for various tasks, such as file I/O, networking, and more. This makes it easy to build complex applications without having to write everything from scratch.
  7. Cross-Platform: Python is a cross-platform language, which means that Python code can run on different operating systems without modification. This makes it easy to develop and deploy Python applications on different platforms.
  8. Community and Ecosystem: Python has a large and active community, which contributes to its ecosystem. There are many third-party libraries and frameworks available for various purposes, making Python a versatile language for many applications.
  9. Versatile: Python is a versatile language that can be used for various purposes, including web development, data science, artificial intelligence, game development, and more.

Here’s a basic guide to get you started with Python:

Install Python

First, you need to install Python on your computer. To install Python on your computer, follow these steps:

  1. Download Python: Go to the official Python website at On the homepage, you will see a “Downloads” section. Click on the “Download Python” button.
  2. Choose the Version: You will be directed to a page where you can choose the version of Python you want to download. Python usually has two main versions available: Python 3. Python 3 is the recommended version. Click on the appropriate version for your operating system (Windows, macOS, or Linux).
  3. Add Python to PATH (Optional): On Windows, you may be given the option to add Python to your system’s PATH environment variable. This makes it easier to run Python from the command line. If you’re not sure, it’s usually safe to select this option.
  4. Install Python: Click the “Install Now” button to begin the installation. The installer will copy the necessary files to your computer.
  5. Verify the Installation: After the installation is complete, you can verify that Python was installed correctly by opening a command prompt (on Windows) or a terminal (on macOS or Linux) and typing python --version. This should display the version of Python you installed.

That’s it! Python should now be installed on your computer, and you’re ready to start using Python.

Setting up a Python Development Environment

An IDE makes coding easier. Popular choices include PyCharm, Visual Studio Code, and Jupyter Notebook. Install one and set it up for Python development. Or you can also use an online Python IDE.

Create and Run your First Python Program

For the first program, we will try to print a very simple message “Hello World” in Python, the code for which is given below:

Once you have Python installed, you can run the program by following these steps:

  1. Open a text editor (e.g., Notepad on Windows, TextEdit on macOS, or any code editor like VS Code, PyCharm, etc.).
  2. Copy the code above and paste it into the text editor.
  3. Save the file with a .py extension (e.g.,
  4. Open a terminal or command prompt.
  5. Navigate to the directory where you saved the file using the cd command (e.g., cd path/to/your/directory).
  6. Run the program by typing python and pressing Enter.

You should see the output “Hello, World!” printed in the terminal.


print("Hello, World!")


Hello, World!

Python Basic Guide

Python has a simple and readable syntax, making it an excellent language for beginners. Here are some basics of Python syntax:


Comments in Python start with the # symbol and are used to explain code or make notes. Comments are ignored by the Python interpreter.

# This is a comment
print("Hello, World!")  # This is another comment


Variables are used to store data. In Python, you don’t need to declare the data type of a variable explicitly. Python will automatically infer the data type based on the value assigned to the variable.

x = 10  # Integer
y = 3.14  # Float
name = "John"  # String

Data Types

Python supports various data types, including integers, floats, strings, lists, tuples, dictionaries, and more.

  • Integers: Whole numbers without decimals.
  • Floats: Numbers with decimals.
  • Strings: Text enclosed in single or double quotes.
  • Lists: Ordered collections of items.
  • Tuples: Immutable collections of items.
  • Dictionaries: Key-value pairs.


Python uses indentation to define blocks of code, such as loops and functions. Use four spaces for indentation. Incorrect indentation can lead to syntax errors.

if x > 10:
    print("x is greater than 10")
    print("x is less than or equal to 10")


Python supports various operators, including arithmetic, comparison, logical, and assignment operators.

  • Arithmetic operators: +, -, *, /, %, ** (exponentiation), // (floor division).
  • Comparison operators: ==, !=, <, >, <=, >=.
  • Logical operators: and, or, not.
  • Assignment operators: =, +=, -=, *=, /=, %=, **=, //=.
  • Bitwise operators: &, |, ^, ~, <<, >>.
  • Strings: Strings can be enclosed in single or double quotes. You can use the + operator to concatenate strings.
    greeting = "Hello"
    name = "John"
    message = greeting + ", " + name + "!"
    print(message)  # Output: Hello, John!

Control Flow

Python supports various control flow structures, such as if-else statements, loops, and more.

  • If-else statement
    if x > 10:
        print("x is greater than 10")
        print("x is less than or equal to 10")
  • For Loops
    for var in iterable:    # statements
  • While Loop
    while expression:


Functions are blocks of code that perform a specific task. You can define your own functions using the def keyword.

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

Remember, Python is a dynamically typed language, so you don’t need to declare the data type of a variable explicitly. Python also uses whitespace (indentation) to define blocks of code, which is different from many other programming languages.
