path should be string, bytes, os.PathLike or None, not list

This error occurs when a list is passed as an argument where a string, bytes, os.PathLike or None value is expected.

For example, let's say you have the following code:

import os

path_list = ['/home/user/documents', 'file.txt']

os.path.join(path_list)

In this code, we are trying to join two paths using the `os.path.join()` method. However, we have passed a list (`path_list`) as an argument instead of a string or bytes value. This will result in the "TypeError: path should be string, bytes, os.PathLike or None, not list" error.

To fix this error, we need to pass a string or bytes value to the `os.path.join()` method. We can do this by either joining the paths manually using string concatenation or converting the list to a string using the `join()` method before passing it to `os.path.join()`.

Here's an example of how we can fix the above code:

import os

path_list = ['/home/user/documents', 'file.txt']

path = os.path.join(*path_list)

In this code, we have used the `*` operator to unpack the `path_list` list and pass its values as separate arguments to the `os.path.join()` method. This will result in the `path` variable containing the joined path as a string value.
