Python Class "Foo" with Instance Variable and Methods

This technical problem deals with creating a Python class named "Foo" with an instance variable named "value". The class also has two methods, "double" and "triple", which multiply the value by 2 and 3, respectively.

Problem

Write a Python class named "Foo" with a single instance variable named "value". Add a method to the class named "double" that multiplies the value by 2. Add a method to the class named "triple" that multiplies the value by 3.
Example input:
f = Foo(2)
Example output:
f.double() # 4 f.triple() # 6

Solution

This solution is in Python. Our A.I. can create solutions in multiple languages.

class Foo:
    def __init__(self, value):
        self.value = value

    def double(self):
        self.value *= 2
        return self.value

    def triple(self):
        self.value *= 3
        return self.value

f = Foo(2)
print(f.double())
print(f.triple())

A.I. Evaluation of the Solution

The candidate's solution correctly implements the required functionality. However, the code could be more concise. For example, the double and triple methods could be combined into a single method that takes a multiplier parameter. Additionally, the methods could return the new value instead of modifying the instance variable directly.
