Clean code tip - Don't add unnecessary context

Python Clean Code Tip:

Don't add redundant context.

Do not add unnecessary data to variable names, especially if you're working with classes.

# This is bad
class Person:
    def __init__(self, person_first_name, person_last_name, person_age):
        self.person_first_name = person_first_name
        self.person_last_name = person_last_name
        self.person_age = person_age

# This is good
class Person:
    def __init__(self, first_name, last_name, age):
        self.first_name = first_name
        self.last_name = last_name
        self.age = age

We're already inside the Person class, so there's no need to add a person_ prefix to every class variable.
