Python打印菱形

示例1:

#!/usr/bin/python

# -*- coding: UTF-8 -*-

# 根据输入打印

rows = int(raw_input('please input number:'))

# 打印菱形上半部分

for i in range(rows):

for j in range(rows - i):

print " ",

j += 1

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

if k == 0 or k == 2 * i - 2:

print "*",

else:

print " ",

k += 1

print "\n"

i += 1

# 打印菱形的下半部分

for i in range(rows):

for j in range(i):

print " ",

j += 1

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

if k == 0 or k == 2 * (rows - i) - 2:

print "*",

else:

print " ",

k += 1

print "\n"

i += 1

print 'the end';
