Python: Join one or more path components together and split a given path in directory and file
Python Operating System Services: Exercise-13 with Solution
Write a Python program to join one or more path components together and split a given path in directory and file.
Sample Solution:
Python Code :
import os
path = r'g:\\testpath\\a.txt'
print("Original path:")
print(path)
print("\nDir and file name of the said path:")
print(os.path.split(path))
print("\nJoin one or more path components together:")
print(os.path.join(r'g:\\testpath\\','a.txt'))
Sample Output:
Original path: g:\\testpath\\a.txt Dir and file name of the said path: ('', 'g:\\\\testpath\\\\a.txt') Join one or more path components together: g:\\testpath\\/a.txt

Previous: Write a Python program to test whether a given path exists or not. If the path exist find the filename and directory portion of the said path.
Next: Write a Python program to alter the owner and the group id of a specified file.

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
