What is the purpose of the "self" keyword when defining or calling instance methods?
Answer: self refers to the instance whose method was called.
Example:
class my_secrets:
    def __init__(self, password):
        self.password = password
        pass
instance = my_secrets('5678')
instance.password
>>>'5678'
