input: Write a function to design a positive feedback loop for a Python program that prints "hello" 10 times. If the loop completes successfully, print "You've got it!". If the function is called without any modifications, it should return the original program with the feedback loop added.
  assert positive_feedback_loop()=='for i in range(10):\\n    print("hello")\\n    i += 1\\n    if i == 10:\\n        print("You\'ve got it!")'
  assert positive_feedback_loop()=='for i in range(10):\\n    print("hello")\\n    i += 1\\n    if i == 10:\\n        print("You\'ve got it!")'
output: def positive_feedback_loop():
      return 'for i in range(10):\n    print("hello")\n    i += 1\n    if i == 10:\n        print("You\'ve got it!")'
