Question

我试图将一个函数用作另一个函数中的参数，但我不断收到错误消息。你们能看看我的代码吗？

#Program used to reverse the order of a string.

sentence = input("Write a sentence. After you click enter it will be returned in reverse order. ")
userInputList = [ ]
reverseInputList = [ ]

#remove any periods from the sentence.
def remove(sentence):
  stripped = sentence.replace(".", "")
  return stripped

#print string in reverse order
def convertList(stripped):
  userInputList = stripped.split()
  reverseInputList = userInputList[::-1]

  for i in range(len(reverseInputList)):
   print (reverseInputList[i], end=" ")


remove(sentence)

convertList(remove())

Answer 1

我不知道您想要的错误，但是我看到错误：

您必须将remove(sentence)的结果分配给变量，并在convertList()中使用此结果

result = remove(sentence)

convertList(result)

或者您必须直接在remove(sentence)中使用带有参数convertList()的函数

convertList(remove(sentence))

如何在函数中使用函数作为参数？
