Wie lange hast du programmiert, bis du in deinem Code Schönheit und Mächtigkeit zu sehen begonnen hast?

Clean code or clean architecture makes your code more readable and predictable.

In this context, comments may also be dispensed with – unless these comments serve a legal purpose. If someone claims he writes a good code and uses comments, then the code is not good.

What would you like better?

import re

class PasswordValidator:
    def __init__(self, password):
        self.password = password

    def __validate_password(self):
        pattern = r"^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{8,}$"
        result = re.match(pattern, self.password)
    
        return result.group()

    def validate(self):
        try:
            self.__validate_password()

            print("Password is valid!")
        except AttributeError:
            print("Password validation failed.")

o_validator = PasswordValidator("aTest1337!")
o_validator.validate()

or

class PasswordValidator:
    def __init__(self, password):
        self.password = password

    def __validate_password_length(self):
        ...

    def __validate_upper_case(self):
        ...

    def __validate_lower_case(self):
        ...

    def __validate_digits(self):
        ...

    def __validate_special_chars(self):
        ...

    def validate(self):
        try:
            self.__validate_password_length(self):
            self.__validate_upper_case(self):
            self.__validate_lower_case(self):
            self.__validate_digits(self):
            self.__validate_special_chars(self):
            
        except AttributeError:
            print("Password validation failed.")

o_validator = PasswordValidator("aTest1337!")
o_validator.validate()

At this point, taste and experience are crucial. Would you know what’s happening? Or would comments be necessary?
