9. Turn the following code into a function. It finds the name in a string and prints it. Pass in the string and return the name if it is found and “Unknown” if not. Be sure to call the function to test it. Test it both when the name is there and when it isn’t.

   namePart = "name: Anu Gao" posName = namePart.find("name:") if (posName > -1): name = namePart[posName+6:len(namePart)] else: name = "Unknown" print(name)
