I am not familiar with Python, but for your current requirement (i.e. backup). I'd strongly 
recommend you to use PowerShell for two reasons:

MS in its SQLPS module (since SQL Server 2012), has a native cmdlet called

Backup-SQLDatabase

You may run this cmdlet on one central server to do the backup against multiple sql instances 
at once because this Backup-SQLDatabase can accept multiple sql instances, like the following example

Backup-SQLDatabase -Database master -Server "my_server1", "my_server2" ...
This 2nd point may help you to centralize all those backup scripts to one administration 
server (dedicated for DBA use) instead of sparsely stored on each sql server instance.

Also with MS providing Backup-SQLDatabase, you can be assured that it will be supported for 
all future new features. (For example, using this cmdlet to support Azure SQL Database etc.)

From: http://www.midnightdba.com/Jen/2010/09/tip-restore-with-filelistonly-with-move/

Use RESTORE FILELISTONLY to get the logical names of the data files in the backup. 
This is especially useful when you’re working with an unfamiliar backup file.
Example:
   RESTORE FILELISTONLY
   FROM DISK = '\\srv1\sql\ImportantDB.bak'

Use RESTORE WITH MOVE to move and/or rename database files to a new path.
Example:
   RESTORE DATABASE ImportantDB
   FROM DISK = '\\srv1\sql\ImportantDB.bak’
   WITH MOVE ‘ImportantDB’ TO ‘F:\SQL\ImportantDB.mdf’,
   MOVE ‘ImportantDB_log’ TO ‘G:\SQL\ImportantDB_log.LDF’

VeryGood: https://community.spiceworks.com/how_to/17736-run-powershell-scripts-from-task-scheduler

powershell.exe -executionpolicy bypass -file "Set-PowerShellScript.ps1"

On the system that the task will be run from, open the Windows Task Scheduler. This can be found 
in the Start menu, under Start > Administrative Tools.
In the Task Scheduler, select the Create Task option under the Actions heading on the right-hand 
side.
Enter a name for the task, and give it a description (the description is optional and not required).
In the General tab, go to the Security options heading and specify the user account that the task 
should be run under. Change the settings so the task will run if the user is logged in or not.
Next, select the Triggers tab, and click New to add a new trigger for the scheduled task. This new 
task should use the On a schedule option. The start date can be set to a desired time, and the 
frequency and duration of the task can be set based on your specific needs. Click OK when your 
desired settings are entered.
Next, go to the Actions tab and click New to set the action for this task to run. Set the Action 
to Start a program.
In the Program/script box enter "PowerShell."In the Add arguments (optional) box enter the value ".
Then, in the Start in (optional) box, add the location of the folder that contains your PowerShell 
script. In this example, the script is in a folder called "Script" that is off the root C: drive.  
Note: The location used in the Start in box will also be used for storing the scheduled task run times, 
the job history for the copies, and any additional logging that may occur. Click OK when all the desired 
settings are made.
Next, set any other desired settings in the Conditions and Settings tabs. You can also set up additional 
actions, such as emailing an Administrator each time the script is run.
Once all the desired actions have been made (or added), click OK. The task will be immediately set, and is 
ready to run.

Just go anywhere on your system and create an empty text file named anything but instead of txt 
make sure the extension is UDL.  Then, double-click on the file and up pops a SQL connectivity 
window to allow testing of remote SQL connections.
