Python Utility Functions for File, Regex, JSON, and Geolocation Operations

These functions are used for generating random strings, reading file content, searching for text with regex, writing file content, calculating the circular distance between two coordinates, creating directories, loading JSON files, saving JSON data, generating timestamps, and determining if a year is a leap year.
