使用 input() 函数时出现 Python 错误 [TypeError: 'str' object is not callable]

Question

notes =[]

def newNote(notes):

    note = input("Whats up")
    notes.append(note)
    return notes

input = input("in or out? ")

if (input == "in"):

    newNote(notes)

note = input("Whats up") is the line that has the problem and I see nothing wrong with it. I have tried the line just by instelf (not in a function) and it works but for some reason it doesnt work inside the function.

Can anyone explain this to me?

Answer 1

The problem with line input = input("in or out? ") .

You redefine input function to result of input("in or out? ") , so now the input is a string.

The solution is to simply change input("in or out? ") result variable to something another:

notes =[]

def newNote(notes):

    note = input("Whats up")
    notes.append(note)
    return notes

choice = input("in or out? ")

if (choice == "in"):

    newNote(notes)

Answer 2

input = input("in or out? ") is overriding the built-in input function. Replace the variable name with a different name and it will work.

Answer 3

Try this:

notes =[]
def newNote(notes):
    note = input("Whats up")
    notes.append(note)
    return notes

inp = input("in or out? ")
if (inp == "in"):
    newNote(notes)

You have used the keyword 'input' to name a variable. You should never use a keyword to define functions or variables unless you want to override the built in functionality of the language.
