I recently started learning Python language and the textbook I have, while presenting the os module, explained how to use the os.name attribute in order to determine the root directory of the operative system - so, a hardcoded solution based on the if-elif-else construct.
Just for the sake of practising and start to get keen on this language, I tried to generalise this solution.
I used the os.path.split() function, knowing that splitting the root directory root_dir returns the tuple (root_dir, ''), where the first element is the root directory and the second is the empty string.
Here, I used a support variable my_tuple, initialised to (os.getcwd(), None), which is updated via the use of split() function in a while loop until its second element is ''.
my_tuple = (os.getcwd(), None)
while my_tuple[1] != '':
    my_tuple = os.path.split(my_tuple[0])
root_dir = my_tuple[0]
Clearly, this is a clumsy solution, for which reason I was wondering if there's a cleaner - and a more Pythonic - way to achieve the goal.
For example, if one imports the pathlib module, they may use the PurePath.root attribute, easy peasy.
Is something similar possible with os module?
