在Windows中，“ with open ...”在计划任务中不起作用

Question

I work with Python on Linux, but I'm forced to schedule a task on Windows. I was having a hard time automating my scripts here. The best alternative for cron I have found is this command

schtasks /Create /SC MINUTE /TN TestTask_Python /TR "C:\\Program Files (x86)\\Python36-32\\python.exe C:\\Users\\user_name\\Desktop\\test.py"

It runs the script every minute and it kind of works. Documentation.

Case 1. Running from IDE. (PyCharm/Idle) Script works.
Case 2. Running from cmd. > python test.py Script works.
Case 3. Runs scheduled task. The script works partially.

Case3 prints not added and it's done, while Case1 and Case2 prints not added , adds datetime to test_time.txt and prints added .

import time
import datetime
import json
from datetime import date

if __name__ == "__main__":

    now = datetime.datetime.fromtimestamp(time.time()).strftime('%Y-%m-%d %H:%M:%S')

    print('not added')
    time.sleep(2)
    with open('test_time.txt', 'a+') as pf:
        pf.write('{0} \n'.format(now))
        print('added')
        time.sleep(1)
    time.sleep(1)

I double checked my enviro variables and python PATH matches the path I put in the schtasks cmd.

Am I missing something? Why with open... doesn't work in this case?

Answer 1

The process has a different working directory when run as a windows task.

Use an absolute path in your call to open() .
