The content of this window will be the same as the paths that are returned when you call sys.path.
When you double click on one, the file editor will open up and you’ll be able to read it. This will let you view the modules that Python IDLE can see.

If you’re interested in reading the source code for a Python module, then you can select File → Path Browser. Then, you can find the Python file you want to open. This will bring up your operating system’s file browser. You can also open an existing Python file by selecting File → Open… in the menu bar. This will open a blank file in the editor, like this:įrom this window, you can write a brand new Python file.
To start a new Python file, select File → New File from the menu bar.

First, let’s take a look at how to write and execute programs in Python IDLE. The built-in file editor also includes several features, like code completion and automatic indentation, that will speed up your coding workflow. Python IDLE offers a full-fledged file editor, which gives you the ability to write and execute Python programs from within this program. The program received the interrupt and has stopped executing. Take a look at what happens when you send a keyboard interrupt to the shell:Ī KeyboardInterrupt error message is displayed in red text at the bottom of your window. This will stop any program or statement that’s running in the shell at the time of interruption. You can also interrupt the execution of the shell from this menu. The shell has forgotten about everything that came before it was restarted. This is an error message that says the variable x is not defined. However, when you restart the shell and try to call print(x) again, you can see that the shell prints a traceback. When you call print(x), the shell shows the correct output, which is the number 5. In the image above, you first declare a variable, x = 5. The shell will forget about everything from its previous state: It will act as though you’ve started a fresh instance of Python IDLE. If you select that option, then you’ll clear the state of the shell. You can restart the shell from this menu. You’ll see a few options for using the shell: You type in commands one at a time and Python responds with the result of each command. This is the most basic way to interact with Python IDLE. Here, you used print() to output the string "Hello, from IDLE!" to your screen. You can test it out with a short line of code: You can use it to start interacting with Python immediately. This is a blank Python interpreter window. When you click on the icon to open the program, the shell is the first thing that you see: The shell is the default mode of operation for Python IDLE. If you’re just beginning your Python programming journey, then Python IDLE is a great alternative! How to Use the Python IDLE Shell

Professional IDEs are more robust pieces of software and they have a steep learning curve. Python IDLE also provides several useful features that you’ll see in professional IDEs, like basic syntax highlighting, code completion, and auto-indentation. Python IDLE gives you the ability to create and edit these files with ease. py extension that contain lines of Python code. A File EditorĮvery programmer needs to be able to edit and save text files. You can simplify your workflow with Python IDLE, which will immediately start a Python shell when you open it. You can access it through the terminal or command line app on your machine. The Python shell is an excellent place to experiment with small code snippets. Then, it loops back to read the next statement. It reads a Python statement, evaluates the result of that statement, and then prints the result on the screen. The shell is a basic Read-Eval-Print Loop (REPL). The best place to experiment with Python code is in the interactive interpreter, otherwise known as a shell.
