The glob module finds all pathnames matching a Unix shell-style pattern using wildcards like * (any characters), ? (single character), and [seq] (character ranges), making file discovery and batch operations simple.
The os module provides os.listdir(), os.makedirs(), os.environ, os.path operations, and process management functions for cross-platform system interactions and file operations.
The os module automatically adapts path separators for different operating systems - os.path.join() uses backslashes on Windows and forward slashes on Unix, making your code truly cross-platform without any changes.
