Watch Now This tutorial has a related video course created by the Real Python team. Watch it together with the written tutorial to deepen your understanding: Ways to Start Interacting With Python

There are multiple ways of interacting with Python, and each can be useful for different scenarios. You can quickly explore functionality in Python’s interactive mode using the built-in Read-Eval-Print Loop (REPL), or you can write larger applications to a script file using an editor or Integrated Development Environment (IDE).

In this tutorial, you’ll learn how to:

• Use Python interactively by typing code directly into the interpreter
• Execute code contained in a script file from the command line
• Work within a Python Integrated Development Environment (IDE)
• Assess additional options, such as the Jupyter Notebook and online interpreters

Before working through this tutorial, make sure that you have a functioning Python installation at hand. Once you’re set up with that, it’s time to write some Python code!

Interacting With Python

In this quiz, you'll test your understanding of the different ways of interacting with Python. By working through this quiz, you'll revisit key concepts related to Python interaction in interactive mode using the REPL, through Python script files, and within IDEs and code editors.

Hello, World!

There’s a long-standing custom in computer programming that the first code written in a newly installed language is a short program that displays the text Hello, World! to the console.

In Python, running a “Hello, World!” program only takes a single line of code:

Python print("Hello, World!")
