How to export windows task scheduler historical log using python?

Question

I am trying to export scheduled tasks information for tracking whether any failed tasks and their timings. There is a function on task scheduler for exporting but is there a way to automate the export using python?

Looks like this question has an example of pulling the data you are asking about. https://stackoverflow.com/a/36635050/4734574

Update:

I used the first example from the link and got all the tasks setup on my system. If you aren't seeing all of the tasks it could possibly be a permissions issue with UAC (User Account Control). If this is the case you might want to run your dos/git-bash with administrator permissions.

1. pip install pywin32
2. run the following python script:

task_dump.py

import win32com.client

TASK_ENUM_HIDDEN = 1
TASK_STATE = {0: 'Unknown',
              1: 'Disabled',
              2: 'Queued',
              3: 'Ready',
              4: 'Running'}

scheduler = win32com.client.Dispatch('Schedule.Service')
scheduler.Connect()

n = 0
folders = [scheduler.GetFolder('\\')]
while folders:
    folder = folders.pop(0)
    folders += list(folder.GetFolders(0))
    tasks = list(folder.GetTasks(TASK_ENUM_HIDDEN))
    n += len(tasks)
    for task in tasks:
        settings = task.Definition.Settings
        print('Path       : %s' % task.Path)
        print('Hidden     : %s' % settings.Hidden)
        print('State      : %s' % TASK_STATE[task.State])
        print('Last Run   : %s' % task.LastRunTime)
        print('Last Result: %s\n' % task.LastTaskResult)
print('Listed %d tasks.' % n)

Note: I made no modifications from the original posters post.

3. Run: python task_dump.py > tasks.log
