TypeError: 'int' object is not subscriptable

1、错误描述

E:PycharmProjectscmnvenvScriptspython.exe E:/PycharmProjects/cmn/venv/com.you.cmn/E.py
Traceback (most recent call last):
  File "E:/PycharmProjects/cmn/venv/com.you.cmn/E.py", line 8, in <module>
    if(nums[i] % 2 == 0):
TypeError: 'int' object is not subscriptable

Process finished with exit code 1

2、错误原因

      列表中的索引不能被使用（订阅）

nums = [12,34,45,64,77,89,90,21,34,54];

even = [];
odd = [];
i = 0;
while i < len(nums):
    nums = nums.pop();
    if(nums[i] % 2 == 0):
        even.append(nums[i]);
    else:
        odd.append(num[i]);

3、解决办法

      借助一个中间变量num

nums = [12,34,45,64,77,89,90,21,34,54];

even = [];
odd = [];
i = 0;
while i < len(nums):
    num = nums.pop();
    if(num % 2 == 0):
        even.append(num);
    else:
        odd.append(num);
print(even);
print(odd);


结果：

[54, 34, 90, 64, 34, 12]
[21, 89, 77, 45]
