* MAINT: Used f-string method
Updated the code with f-string methods wherever required for a better and cleaner understanding of the code.
* Updated files with f-string method
* Update rsa_key_generator.py
* Update rsa_key_generator.py
* Update elgamal_key_generator.py
* Update lru_cache.py
I don't think this change is efficient but it might tackle the error as the error was due to using long character lines.
* Update lru_cache.py
* Update lru_cache.py
