Why Are Non-Alphanumeric Lists from os.listdir() Ordered Differently?

Interpreting Non-Alphanumeric Lists from os.listdir()

In Python, the os.listdir() method retrieves a list of the subdirectories in the current working directory. However, users have recently observed a deviation from the expected alphanumeric ordering of the listed directories.

To understand this unusual behavior, one must consider the underlying mechanism that determines the order of these lists. The ordering of files in a directory is largely influenced by the underlying file system. Different file systems may employ unique sorting algorithms, resulting in unpredictable orderings.

To regain the desired order, one can leverage the built-in sorted() function or the sort() method of lists. Here's an example using sorted():

dir = sorted(os.listdir(os.getcwd()))

Alternatively, you can use the following approach with the .sort method:

lst = os.listdir(os.getcwd())
lst.sort()

Both methods should sort the list in a manner consistent with alphanumeric ordering.
