Not sure what is wrong. Tested this in vs.code: All possible inputs return an absolute path from root. Confirming that the path from root to relative are correct. Also if input was not an absolute path it will do get_root() again.
import pathlib
import os
def get_root():
root = pathlib.PurePath(
input("What's the full path where you'd like the project? ")
)
if not root.is_absolute():
return get_root()
test = pathlib.PurePath(root)
pwd = os.getcwd()
if f'{pwd}' == f'{root}' or test.is_relative_to(pwd):
return root
elif f'{pwd}' != f'{root}':
return os.path.abspath(f'{os.getcwd()}{root}')

In this case, the instructions say "The function should always return an absolute path", which implies that the function should no longer call itself or ask for input a 2nd time.

15,408 PointsOk, I'm still having trouble. I get "Got a changed absolute path from an absolute path".
I input the following:
/Users/shawn/teamtreehouse <--- True absolute from root.
Users/shawn/teamtreehouse <--- not absolute, missing '/'
/something/something <-- relative but comes out absolute
something/something <-- bad relative but comes out absolute
All comes out as current working directory path with relative path or just the current directory path.
import pathlib
import os
def get_root():
pwd = os.getcwd()
root = pathlib.PurePath(
input("What's the full path where you'd like the project? ")
)
if not root.is_absolute():
if f'{pwd}' == f'/{root}':
return f'/{root}'
else:
return f'{pwd}/{root}'
if f'{pwd}' == f'{root}':
return f'{root}'
if f'{pwd}' != f'{root}':
return f'{pwd}{root}'

15,408 PointsI'll try to figure out "always return an absolute path". I'll keep you posted.

231,269 PointsAs the instructions also say, "if the path is relative, change it into an absolute path".

231,269 PointsWhen the test
if not root.is_absolute
is not true, the path is absolute and should be returned without modification. But the revised code is still making other tests and may modify the path or possibly not return anything at all.shawn007

15,408 PointsWell after you mentioned "possibly not return anything at all", I noticed that if someone inputs nothing, I'll get a '.' which I'd fixed later. But, It wasn't enough to pass the problem. I had to step back and rethink my code. Turns out it was silly simple and the code challenge didn't care if the path was from root or not. The cause of my troubles was the wording of get_root(). I made all these 'if' statements to try and catch if the path will come from actual root and make sure to return a path that is true from root to the given input. Lots of unnecessary headaches.
Thanks again for the help!!!
