Python.exe stays open after running batch file in task scheduler - windows

Question

I'm trying to schedule in task scheduler:
Run a batch file
Activate a conda environment
Run a python program
Exit command prompt
Everything works fine, except the python.exe window will remain open while the command prompt closes.
My batch file: (the sleep is for the python code to run. It takes a few seconds)
call activate python2
start C:\Users\Chris\Anaconda3\envs\python2\python.exe testtest.py
sleep 30
exit
My python script:
driver = webdriver.Chrome(executable_path="C:\path\to\chromedriver")
driver.get('http://website.com')
# Find email and pw fields and then fill them in
email = driver.find_element_by_id("user_email")
email.send_keys('myemail#email.com')
pw = driver.find_element_by_id("user_password")
pw.send_keys('password')
# Click on sign-in button
driver.find_element_by_class_name("button").click()
time.sleep(5)
# Click on save button to update
driver.find_element_by_class_name("button").click()
# Close driver
driver.close()
Last thing, the program/script is the batch file, no arguments, and the start in is in the directory that the batch file is in.
Any help would be appreciated!

Answer 1

put you python codes in a main() function.
and give:
if __name__ == '__main__':
main()
at the end.
Just tested works for me.

Answer 2

#pk2019 's answer really helped me.
One improvement is to use
drv = webdriver.Chrome()
# Do your things.
...
drv.close()
drv.quit()
No need to do the dirty work of killing task.

Answer 3

I'm not a python expert, but I think you just need to call sys.exit() or quit().
Instead of using sleep and waiting too long or possibly not long enough, call start with the wait option:
call activate python2
start /WAIT C:\Users\Chris\Anaconda3\envs\python2\python.exe testtest.py
exit
If you don't need the batch file to do anything else, you can just start the python script and exit.

I had a similar problem with a Python selenium web scraper running geckodriver.exe Firefox web driver on Windows (executed via Task Scheduler using a .bat file). The problem is that my geckodriver.exe process is still running after the Python script is done ... and I think that running process is preventing the Windows command prompt from closing.
In order to test this hunch, I inserted the tasklist command into the .bat file, both before and after the Python script. It prints out a list of running Windows tasks to the console ... I noticed the geckodriver.exe file was still running the Python script was finished.
The way to kill a Windows process (using taskkill) is described in these two different Stackoverflow responses:
Safely killing a python script on Windows
Batch script to close all open Command Prompt windows
How to close Command Prompt window after Batch file execution in python?
Here is the Windows documentation for taskkill:
https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/taskkill
In my case, I added this as the 2nd to last line: taskkill /im geckodriver.exe /f, and the last line was exit. That worked.
