布尔值不会成为错误的python

Question

boolean = True
print ("Enter your list of numbers. Type \"done\" when you are finished entering all your numbers ")

def collectNumbers(number):


    if number is ("done"):
        boolean == False #but it never actually becomes false
    if boolean == True:
        number = input("Enter a number ")
        listofNumbers.append(number)
        collectNumbers(None)
    else:
        print ("That is not a number. Please drink some bleach.")
        collectNumbers(None)

它返回：

Enter a number 1
Enter a number 2
Enter a number 3
Enter a number 4
Enter a number done
Enter a number done
Enter a number done
Enter a number 

尽管我输入“完成”，它仍然没有突破功能。 “boolean”不会变成“false”，因此函数永远不会爆发。

Answer 1

if number == "done": #change is to == and strip ()
    boolean = False  #change == to =
