How to Make Your Python Script Automatically Close After Running

As a beginner in Python, you might encounter situations where your scripts seem to hang after execution. This can be particularly frustrating, especially if you're planning to run your script as a scheduled task in Windows. One common scenario is when you're using Selenium to scrape data from a website; after the script finishes running, the terminal remains open and does not close automatically. In this post, we’ll address how to solve this issue effectively.

The Problem

Imagine you've written a Python script that pulls vital data from a website and saves it to a text file. However, after running the script, you notice that it just sits there, leaving the terminal open. For someone looking to automate tasks using Windows Task Scheduler, this can be a hassle as you want the script to close on its own after completing its task.

The Initial Code Sample

Let's take a look at the sample code in question:

At first glance, everything seems to have been properly structured, but there is a crucial distinction between driver.close() and its counterpart driver.quit() in handling the browser session.

The Solution: Understanding Driver Methods

In this scenario, the main reason your terminal was hanging is due to the difference between driver.close() and driver.quit().

driver.close()

Purpose: This method is intended to close the browser window that the driver has opened.

Limitation: It does not terminate the chromedriver process. While it may close the visible browser window, the script itself may still hang because the chromedriver background process is still running.

driver.quit()

Purpose: This method closes all browser windows and effectively shuts down the chromedriver process.

Benefit: Using this method ensures that there are no lingering processes left running after your script finishes, enabling the terminal to close automatically after execution.

Updated Code

To modify the script to ensure it closes effectively, simply replace the driver.close() line with driver.quit(). Here’s the updated section of the code:

Conclusion

By implementing driver.quit() instead of driver.close(), you allow your script to terminate properly without leaving any hanging processes. This small change solves the problem of your Python script keeping the terminal open after completion.
