程式碼為 def get_formatted_name(first_name, last_name):

	full_name = first_name + ' ' + last_name
	return full_name.title()

while True:

	 print("\nPlease tell me your name:")
	f_name = input("First name: ")
	l_name = input("Last name: ")
	formatted_name = get_formatted_name(f_name, l_name)
	print("\nHello, " + formatted_name + "!")
 

可是這樣下來執行的時候執行結果是空，沒有任何顯示，求大神賜教
