1.九九乘法表

#!/usr/bin/python   for i in range(1,10):    for j in range(i):        j += 1        print ("%d * %d = %-2d  " %(i, j, i*j)),    print ""

2.水仙花

#!/usr/bin/python l = []for a in range (100,1000):    if (a/100%10)**3 + (a/10%10)**3 + (a%10)**3 == a:        l.append(a)print l

3.質數

#!/usr/bin/python l = []for i in range (2,101):    flag = 0    for j in range (2,i-1):        if i % j == 0:            flag = 1            break    if flag == 0:        l.append(i)print l

4.倒敘排列和冒泡排序

#!/usr/bin/python #!coding=utf-8list = [5,8,6,9,3,4,8,9,5,1,4]list_len = len(list)#倒敘排列l_len = list_len/2for i in range(l_len):    list[i],list[list_len-1-i] = list[list_len-1-i], list[i]print list#冒泡排序for i in range(list_len - 1):    for j in range(i,list_len):        if list[i] > list[j]:            list[i],list[j] = list[j],list[i]print list

5.完數

#!/usr/bin/python l = []for i in range (1,1000):    sum = 0    for j in range (1,i):        if i % j == 0:            sum += j    if sum == i:        l.append(i)print l

 6.斐波那契數列

#!/usr/bin/python l = [1,1]for i in range(9):    l.append (l[i] + l[i+1])print l
