Random String Generator and File Operations

The function xxx generates a random string, checks if a file exists, retrieves the current time, converts a dictionary to a JSON string, generates an MD5 hash, matches numbers with regular expressions, calculates an average, and clears all files in a directory.

Technology Stack : The function xxx uses the following Python built-in functions: generate_random_string, os.path.exists, datetime.datetime.now, json.dumps, hashlib.md5, re.compile, sum, map, int, len, and shutil.rmtree.

Code Type : Function

Code Difficulty : Intermediate
