python - 谁能找出这段代码有什么问题？

Question

谁能找出这段代码有什么问题？我从一本书上复制粘贴。

def findSmallestNumber(arr):
    smallestNumber = arr[0]
    for i in range(1,len(arr)):
        if arr[i] < smallestNumber:
            smallestNumber = arr[i]
    return smallestNumber

def sort(arr):
    newArr = []
    for i in range(len(arr)):
        smallestNumber = findSmallestNumber(arr)
        newArr.append(arr.pop(smallestNumber))
    return newArr
    

print (sort([12,32,4,22,6]))

我得到这个输出：

Traceback (most recent call last):
  File "<string>", line 16, in <module>
File "<string>", line 12, in sort

尝试这个：

def sort(arr):
    newArr = []
    for i in range(len(arr)):
        smallestNumber = findSmallestNumber(arr)
        newArr.append(arr[arr.index(smallestNumber)])
        arr.remove(smallestNumber)
    return newArr
