python ACM ，持续更新中。。。。。。。。。。。。

1, C语言实验——图形输出（字符常量练习）:  http://acm.sdut.edu.cn/sdutoj/problem.php?action=showproblem&problemid=1112

python中用print总是会出现回车空格，非常讨厌，然而，Python 3.0下print已经从语句变为函数了，我用的使python2.7.4,所以呢，还不行。。。。。但是我们可以用其他方法：

import sys
sys.stdout.write("abc")
sys.stdout.write("def")

#!/usr/bin/env python
#coding:utf8

import sys

for i in range(1, 6+1):
    for j in range(1, i+1):
        sys.stdout.write("#")
    sys.stdout.write('\n')

2, C语言实验——交换两个整数的值（顺序结构）：http://acm.sdut.edu.cn/sdutoj/problem.php?action=showproblem&problemid=1115

pathon交换两个值非常简单哦，看下面：

#!/usr/bin/env python
#coding:utf8

x, y = raw_input().split()

x , y = y, x
print x,y

3, C语言实验——for循环打印图形（循环结构）： http://acm.sdut.edu.cn/sdutoj/problem.php?action=showproblem&problemid=1121

也许使因为刚使用，所以代码写的有点长，以后看看能不能精简些，欢迎拍砖

#!/usr/bin/env python
#coding:utf8

import sys

for i in range(1,7+1):
    if i<4:
        for j in range(1,5-i):
            sys.stdout.write(" ")
        for j in range(1,2*i):
            sys.stdout.write("*")
        sys.stdout.write("\n")
    elif i==4:
        for j in range(1,7+1):
            sys.stdout.write("*")
        sys.stdout.write("\n")
    else:
        for j in range(1,i-4+1):
            sys.stdout.write(" ")
        for j in range(1,6-2*(i-5)):
            sys.stdout.write("*")
        sys.stdout.write("\n")
