Get the file name and directory from a path in Python

In this example, you see how to get the directory+filename or directory+subdirectory from any given path in Python

To extract the directory and file name in Python, use the os module. The os module has functions basename and dirname. Here is an example on how to use them:

import os

print(os.path.basename("/a/b/c/d"))       # d
print(os.path.basename("/a/b/c/d.txt"))   # d.txt
print(os.path.dirname("/a/b/c/d"))        # /a/b/c
print(os.path.dirname("/a/b/c/d.txt"))    # /a/b/c

print(os.path.basename("/a/b/c/d/"))      # Empty str
print(os.path.dirname("/a/b/c/d/"))       # /a/b/c/d

Output:

d
d.txt
/a/b/c
/a/b/c

/a/b/c/d

Trailing slash

A path that ends with a trailing slash is split at the last slash wich causes the last part to be an empty string.
