AttributeError: 'PosixPath' object has no attribute 'endswith'

This error occurs when you try to use the method "endswith()" on a PosixPath object, which is not supported.

To fix this error, you can convert the PosixPath object to a string using the "str()" method, and then use the "endswith()" method on the resulting string.

For example:

import pathlib

path = pathlib.Path('/path/to/file.txt')

# Convert the PosixPath object to a string
path_str = str(path)

# Use the "endswith()" method on the string
if path_str.endswith('.txt'):
    print('File is a text file.')
else:
    print('File is not a text file.')

Output:

File is a text file.
