Random File Event Handler in Watchdog Monitoring

This code defines a function named watch_directory that uses the watchdog library to monitor file change events in a specified directory. When a file is modified, created, or deleted, it will call the random_file_event_handler function to handle the event. This function randomly selects different handling methods, such as printing the file path and event type, or calling the custom random_file_event_handler function.

Technology Stack : The code uses the watchdog library and the following technologies: Python programming language, Observer pattern, FileSystemEventHandler, and lambda functions.
