How to find the common parent directory of multiple file paths using the path package?

To find the common parent directory of multiple file paths using the path package, you can follow these steps:

Import the path module from the pathlib package:

from pathlib import Path

Create a list of file paths that you want to find the common parent directory for:

file_paths = ['/path/to/file1.txt', '/path/to/file2.txt', '/path/to/folder/file3.txt']

Convert the file paths to Path objects:

path_objects = [Path(file_path) for file_path in file_paths]

Use the Path object's parents attribute to get a list of the parent directories for each file path:

parent_directories = [path.parents for path in path_objects]

Get the common parent directory by finding the intersection of all the parent directories:

common_parent = set.intersection(*parent_directories)

If the common_parent set is not empty, get the first element as the common parent directory path:

if common_parent:
    common_parent_directory = common_parent.pop()
    common_parent_directory = str(common_parent_directory)  # Convert Path object to string

Here is the complete code:

from pathlib import Path

file_paths = ['/path/to/file1.txt', '/path/to/file2.txt', '/path/to/folder/file3.txt']

path_objects = [Path(file_path) for file_path in file_paths]

parent_directories = [path.parents for path in path_objects]

common_parent = set.intersection(*parent_directories)

if common_parent:
    common_parent_directory = common_parent.pop()
    common_parent_directory = str(common_parent_directory)  # Convert Path object to string

print(common_parent_directory)

Running this code will print the common parent directory path.
