  class Person:

          self.name = name
          self.age = age
          self.email = email
      
      def toString(self):
          return f"Name: {self.name}, Age: {self.age}, Email: {self.email}"
  
  # Test cases
  person1 = Person("Alice", 30, "alice@example.com")
  assert person1.toString() == "Name: Alice, Age: 30, Email: alice@example.com"
  
  person2 = Person("Bob", 25, "bob@example.com")
  assert person2.toString() == "Name: Bob, Age: 25, Email: bob@example.com"
  
output: class Person:
      
      def __init__(self, name, age, email):
          self.name = name
          self.age = age
          self.email = email
