1. 打印三角形

分为三角形，倒三角形和等腰三角形

#coding:utf-8

rows = int(raw_input("please input a number:"))

i = j = k = 1

print "直角三角形"

for i in range(0,rows):

for k in range(0,i + 1):

print "*",

k += 1

i += 1

print "\n"

rows = int(raw_input("please input a number:"))

print "直角三角形"

for i in range(0,rows):

for k in range(0,rows - i):

print "*",

k += 1

i += 1

print "\n"

print '等腰三角形'

for i in range(0,rows + 1):

for j in range(0,rows - i):

print " ",

j += 1

for k in range(0,2 * i - 1):

print "*",

k += 1

print "\n"

i += 1

2. 求1000以内的完全数有哪些

#coding:utf-8

list_num = []

num = 1000

for i in range(1,num + 1):

if sum([a for a in range(1,i) if i % a == 0]) == i:

list_num.append(i)

print i

print list_num

** 3. 打印万年历**

#coding:utf-8

#打印万年历

#1.判断是否为闰年

#2.计算每种情况下，每个月份的天数

#3.由2计算每年的天数

#4.计算每月一日对应的星期，基于1990年1月1日是星期一
