Python打印等边三角形
示例1:
#!/usr/bin/python
# -*- coding: UTF-8 -*-
# 根据输入打印
rows = int(raw_input('please input number:'))
# 等边三角形
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):
if k == 0 or k == 2 * i - 2 or i == rows:
if i == rows:
if k % 2 == 0:
print "*",
else:
print " ",
else:
print "*",
else:
print " ",
k += 1
print "\n"
i += 1
print 'the end';
