选择排序python实现

def findsmallest(arr):
    smallest=arr[0]
    smallest_index=0
    for i in range(1,len(arr)):
        #smallest_index+=1
        if arr[i]<=smallest:
            smallest=arr[i]
            smallest_index=i
    return smallest_index
def selectionsort(arr):
    l=[]
    for i in range(len(arr)):
        smallest=findsmallest(arr)
        l.append(arr.pop(smallest))
    return l
a=[7,4,8,2,9]
print(selectionsort(a))
pop()用法括号中是index
