😁😀Challenge: Happy numbers! 😀😁

Question

A happy number is defined by the following process:

Starting with any positive integer, replace the number by the sum of the squares of its digits, and repeat the process until the number equals 1 where it will stay), or it loops endlessly in a cycle which does not include 1.

Those numbers for which this process ends in 1 are happy numbers, while those that do not end in 1 are unhappy (or sad) numbers.

A happy prime is a number that is both happy and prime.

Find both happy numbers and happy prim

Answer 1

My Code: Using Python ☆

The best thing about it (objectively talking) is the proper handling of the endless loop for the unhappy numbers (No Limit Error)

However, I didn't test it that much, so in case of an error or bug please tell me ^^

Hope u Like it ♡
