input: Write a function to create a Python class named "Person" with attributes "name" (string), "age" (integer), and "email" (string). Include a method named "toString" that returns a string with the formatted attributes.
  class Person:
      
      def __init__(self, name, age, email):
          self.name = name
          self.age = age
          self.email = email
      
      def toString(self):
          return f"Name: {self.name}, Age: {self.age}, Email: {self.email}"
  
  assert Person("John", 30, "john@example.com").toString() == "Name: John, Age: 30, Email: john@example.com"
  assert Person("Alice", 25, "alice@example.com").toString() == "Name: Alice, Age: 25, Email: alice@example.com"
output: 
  class Person:
      
      def __init__(self, name, age, email):
          self.name = name
          self.age = age
          self.email = email
      
      def toString(self):
          return f"Name: {self.name}, Age: {self.age}, Email: {self.email}"
