我试图在Windows10上用Python3.6.5编写一个程序，它接受整数，然后打印出奇数。在

这是我的代码：def listInput():

aList = list()

while True:

num = input("Please input a number:")

if num == 'done':

break

num = int(num)

aList.append(num)

return aList

def isOddNumber(y):

if y%2 == 0:

return False

else:

return True

def filterOddInList(a):

i = len(a)

while i >= 0:

item = a[(i-1)]

odd = filterOddInList(item)

if odd == False:

x.pop()

def main():

a = listInput()

print(a)

a = filterOddInList(a)

print(a)

main()

这是应该发生的事情：

^{pr2}$

实际情况如下：Please input a number:1

Please input a number:2

Please input a number:3

Please input a number:4

Please input a number:5

Please input a number:done

[1, 2, 3, 4, 5]

Traceback (most recent call last):

File "C:\Users\Jerry Cui\Documents\New folder\Homework\oddonly.py", line 30, in

main()

File "C:\Users\Jerry Cui\Documents\New folder\Homework\oddonly.py", line 27, in main

a = filterOddInList(a)

File "C:\Users\Jerry Cui\Documents\New folder\Homework\oddonly.py", line 20, in filterOddInList

odd = filterOddInList(item)

File "C:\Users\Jerry Cui\Documents\New folder\Homework\oddonly.py", line 17, in filterOddInList

i = len(a)

TypeError: object of type 'int' has no len()

有人能告诉我这个错误发生的原因吗？正确的代码应该是什么？在
