Generating Random Data with Timestamp and Hashing

This code first uses the datetime module to get the current timestamp, then uses the random and string modules to generate a random string. Then, it uses the hashlib module to perform a SHA-256 hash on the timestamp and random string to generate a hash value. Finally, it uses the json module to convert the timestamp, random string, and hash value into a JSON format and write it to a file, then copy the file to a new directory, run a subprocess to get the Python version, and finally delete the original file.
