input: Write a Python class named Person with the attributes name (string), age (integer), and email (string). The class should include a function toString() that returns a string with the formatted attributes in the format "Name: {self.name}, Age: {self.age}, Email: {self.email}".
  
  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("Jane", 25, "jane@example.com").toString()=="Name: Jane, Age: 25, Email: jane@example.com"
  assert Person("", 0, "").toString()=="Name: , Age: 0, Email: "
output: 
  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}"
