How to Run Python?

If you want to get started with Python quickly, try our online Python editor to run code. It is used by millions of users to run tens of millions of Python programs every month.

The editor runs in your browser and it also includes a powerful code visualizer that helps you understand how your code works.

Your First Python Program

Often, a program called "Hello, World!" is used to introduce a new programming language to beginners. A "Hello, World!" program is a simple program that outputs "Hello, World!" on the screen.

Since Python has very simple syntax, creating this program can be done in a single line: print("Hello, World!"). So instead, we are going to write a different program to add two numbers as our first program.

number1 = 5
number2 = 10
total = number1 + number2
print(result)

Run the above program and see the output for yourself. Here's how this program works:

Line 1: number1 = 5

Here, number1 is a variable (used for storing values). The value stored in number1 is 5.

Line 2: number2 = 10

The value stored in number2 is 10.

Line 3: total = number1 + number2

The values stored in number1 and number2 are added using the + operator. The result of the addition is then assigned to another variable, total.

Line 4: print(total)

The print() function displays the value stored in total, which is 15.

If you don't completely understand this program, that's fine. Our tutorials cover bits and pieces of this program step by step.

Using AI to learn Programming

There is no denying that AI (LLMs) have gotten better and better since ChatGPT-3 was introduced to the public in 2022.

You will probably use AI to learn Python concepts, that's perfectly fine. However, one thing you must certainly do is write, edit and run code yourself as you go along. No matter how much you study, you cannot get better at coding without writing code yourself.

If you run into problems, and you will, try to fix them yourself first. It's the only way you'll get better at programming. You can always use AI later if you get really stuck and can't figure it out.

We also recommend trying our code visualizer/compiler (it's free and doesn't require an account). It lets you step through code and you can exactly see what's happening at every step. Helps you with your learning.
