計(jì)算1-100之和

運(yùn)算結(jié)果:

冒泡排序ptyhon版：

#bubble.py def bubble(li):temp = 0for i in range(len(li) - 1):for j in range(len(li) - 1 - i):if li[j] > li[j + 1]:temp = li[j]li[j] = li[j + 1]li[j + 1] = tempelse: temp = li[j+1]print(li)

bubble([123,345,12,27,48,846,3458,239,9342])

?

運(yùn)行結(jié)果：

robot@ubuntu:~/wangqinghe/python$ python3.5 bubble.py

[12, 27, 48, 123, 239, 345, 846, 3458, 9342]

選擇排序：

#select.py a=[1,5,4,2,2,31,12,7,4] b = list(set(a)) c = [] for j in b:for i in a:if i == j:c.append(i) print(c)a = [1,23,457,234,68,234,47,925,345] print("primary a : ",a) a.sort() print(a)

運(yùn)行結(jié)果：

robot@ubuntu:~/wangqinghe/python/20190827$ python3.5 select.py

[1, 2, 2, 4, 4, 5, 7, 12, 31]

primary a :? [1, 23, 457, 234, 68, 234, 47, 925, 345]
