python实现选择排序

list_1 = []       #先建一个空链表
print('输入排序个数：')
n = int(input())   #接收输入个数
for i in range(n):
    a = input()
    list_1.append(a) #将这n个数都存入链表
Lenth = len(list_1) 
for i in range(Lenth - 1):  
    Min = list_1[i]  #假设第一个数为最小值
    k = i
    for j in range(i+1, Lenth, 1): #内循环遍历，将最小的数排好，依次类推
        if Min > list_1[j]:
            Min = list_1[j]
            k = j
    list_1[i], list_1[k] = list_1[k], list_1[i]
print(list_1)
