如何在函数中使用函数作为参数？

Question

I am trying to use a function as a parameter in another function but I keep getting an error. Can you guys please take a look at my code.

#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

I don't know want error you get but I see mistake:

you have to assign result from remove(sentence) to variable and use this result in convertList()

result = remove(sentence)

convertList(result)

or you have to use function with argument remove(sentence) directly in convertList()

convertList(remove(sentence))
