A developer is refactoring a function that currently has many positional parameters. The team wants to improve readability and reduce errors when calling the function. They also need to maintain backward compatibility with existing calls. Which strategy is most effective?

Introduce keyword-only parameters for new options while keeping existing positional parameters unchanged.

Keep the positional parameters but add default values to all of them.

Convert all parameters to keyword-only arguments by placing them after a '*' in the signature.

Replace the parameters with a single **kwargs dictionary.

A developer is implementing a 'User' class with a 'password' attribute. They want to prevent accidental modification of the password after the user is created, but still allow reading it. Which approach best achieves this?

Use a regular attribute and rely on the developer to not modify it.

Use a static method to set the password and call it from the constructor.

Define a property with a getter and no setter, storing the password in a name-mangled attribute like 'self.__password'.

Define a class attribute 'password' and set it in the constructor.
