Now I need you to write a function named absolute that takes two arguments, a path string and a root string. If the path is not already absolute, return the path with the root prepended to it.
For example: absolute("projects/python_basics/", "/") would return "/projects/python_basics/" while absolute("/home/kenneth/django", "C:\") would return "/home/kenneth/django".
>>>> import os
>>>> os.path.absolute("projects/python_basics/", "C:/home/kenneth/django")

28,054 PointsYes you have to. Ok, so I will walk you through my solution.
def absolute(path, root):
if(not os.path.isabs(path)):
new_path = ''.join((root, path))
return new_path
else:
return path
I define the function "absolute" that takes two arguments - a path and a root (since POSIX and Windows use different root-signatures). I then check if the path that was passed in is NOT an absolute path. I do this with the "abs" method from the "os.path" package. If it's not an absolute path, I create a new variable that will hold the value of the path prepended with the root (I do this with the built in join function on a empty string), and then i return the variable. However, if the path is an absolute path, i.e. if the IF-statement returns False, then I just return the path that was passed in as it is.

28,054 PointsImport os and create a function that takes two arguments like so
import os
def absolute(path, root):
pass
Now use the isabs method from os.path and check if the path that was passed in is NOT an absolute path. If it's not, prepend the root-argument to the path and return the new path (with pythons join-method for instance). Else return the path as it is.

61,838 PointsThank you for response. i want to know if i have to put it in an IF else statement, to determine the result wanted?
import os
def absolute(path, root):
pass
os.path.isabs("/home/kenneth/django")
os.path.isabs("projects/python_basics/")
os.path.join("projects/python_basics/", "/")

61,838 PointsThank you Johan,
Now I understand, just didnt know how to implement it
