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';
