类型错误：“str”对象在输入行上不可调用

Question

I'm a Python beginner looking for some help with this piece of code:

elif exit is False and temp is ('1'):
add_more = True
add_1 = 'y'
while add_more is True:
    races.append(input('What is the name of the race: '))
    print('Racelist is now: ' + str(races))
    add_1 (input('Want to add more? yn '))
    if add_1 is ('y'):
        add_more = True
    else:
        addmore = False

When I run it I keep getting the following error:

Traceback (most recent call last):
  File "C:/Users/David/PycharmProjects/Eclipse/Eclipse.py", line 43, in <module>
    add_1 (input('Want to add more? yn '))
TypeError: 'str' object is not callable

When I comment out the affected line the loop works and keeps asking: races.append(input('What is the name of the race: ')) (the variable races is a list).

I've been breaking my neck on it all night and google was no help so far. I cannot understand why the line does not work but the other input does work. .

It seems there are a few things wrong in your code. In the else statement you set addmore = False , i assume this is meant to be add_more = False . Also i assume that you want to allocate the user response to the variable add_1. Lastly you should not use is to compare values. Instead use the == or != type comparisons. You could try the following

add_more = True
add_again = 'y'
while add_more:
    races.append(input('What is the name of the race: '))
    print('Racelist is now: ' + str(races))
    add_again = input('Want to add more? yn ')
    if add_again.lower() != 'y':
        add_more = False
