python选择,冒泡,插叙排序方式

选择排序:import randomdef select_sort(li): for i in range(len(li) - 1): min_loc = i for j in range(i+1, len(li)): if li[min_loc] > li[j]: min_loc = j if min_loc != i: li[i] , li[min_loc] = li[min_loc] , li[i]
data = list(range(1000))random.shuffle(data)select_sort(data)print(data)

冒泡排序:import random
# def bubble_sort(li):# for i in range(len(li) - 1):# for j in range(len(li) - i - 1):# if li[j] > li[j+1]:# li[j], li[j+1] = li[j+1], li[j]
def bubble_sort_1(li): for i in range(len(li) - 1): exchange = False for j in range(len(li) - i - 1): if li[j] > li[j+1]: li[j], li[j+1] = li[j+1], li[j] exchange = True if not exchange: break

data = list(range(1000))random.shuffle(data)# bubble_sort(data)bubble_sort_1(data)print(data)

插叙排序:# import random# def insert_sort(li):# for i in range(1,len(li)):# tmp = li[i]# j = i - 1# while j >= 0 and li[j] < tmp:# li[j+1]=li[j]# j = j - 1# li[j+1] = tmp## data = list(range(1000))# random.shuffle(data)# insert_sort(data)# print(data)
num1 = [36,52,1,9,43]for i in range(1,len(num1)): j = i - 1 if num1[i] < num1[j]: temp = num1[i] num1[i] = num1[j]
j = j - 1 while j >= 0 and temp < num1[j]: num1[j+1] = num1[j] j = j - 1 num1[j+1] = tempprint(num1)
