How do Iexit Python in terminal? When I type exit in the Python command line, I get the message:

Use exit() or Ctrl-Z plus Return to exit

Why doesn’t the interpreter exit when I type exit directly, especially when it’s clear that I’m trying to exit the command line? Instead, it prompts me to use exit() or Ctrl-Z. Why doesn’t it just exit when I type exit? I know it’s not a big issue, but I’m curious.

So, here’s what I’ve learned over the years about exiting Python. The exit() function is the official way to quit the Python interpreter. It’s part of the sys module and ensures a clean termination of the session. That’s why, when you type just exit, the interpreter nudges you to use exit() instead. It’s like Python reminding you to follow the proper method for shutting things down.

Example:

>>> exit()

This is one of the simplest approaches when you’re figuring out how to exit Python in terminal.

Adding to what @emma-crepeau said, if you’re working in a terminal, there’s another handy method for how to exit Python in terminal without typing exit().

On Windows, you can press Ctrl-Z and then hit Enter. On Unix/Linux systems, pressing Ctrl-D does the job. These shortcuts send an EOF (End Of File) signal to Python, effectively ending the interpreter session.

Example:

  • Windows: Press Ctrl-Z + Enter.
  • Unix/Linux: Press Ctrl-D.

I find this particularly useful when I’m working directly in a command-line terminal—it saves a few keystrokes compared to typing exit().

Building on what @vindhya.rddy and @emma-crepeau mentioned, here’s why exit doesn’t work on its own. When you type just exit, Python treats it as a variable name or an uncalled function, not as the actual command to terminate. That’s why you get that little reminder to use exit() instead.

Python designed exit() as a proper function to ensure a clean shutdown, avoiding any unintentional terminations. However, if you want a quicker alternative, the Ctrl shortcuts Toby mentioned work great for how to exit Python in terminal.

So, in summary:

  1. Use exit() for clarity.
  2. Use Ctrl-Z (Windows) or Ctrl-D (Unix/Linux) for speed.
