python程序的输入输出(acm的几个小程序)
1, A+B Problem : http://acm.sdut.edu.cn/sdutoj/problem.php?action=showproblem&problemid=1000
#!/usr/bin/env python # coding=utf-8 a=[] for x in raw_input().split(): a.append(int(x)) print sum(a)
下面的代码只有一行,,可惜不是我想出来的!!!!:
print sum(int(x) for x in raw_input().split())
2, A+B for Input-Output Practice (I) : http://acm.sdut.edu.cn/sdutoj/problem.php?action=showproblem&problemid=1010
while True: a=[] line = raw_input() if line: for x in line.split(): a.append(int(x)) print sum(a) else: break
3, A+B for Input-Output Practice (II) : http://acm.sdut.edu.cn/sdutoj/problem.php?action=showproblem&problemid=1011
#!/usr/bin/env python #coding:utf8 t = int(raw_input()) while t>0: a=[] for x in raw_input().split(): a.append(int(x)) print sum(a) t=t-1
4, A+B for Input-Output Practice (III) : http://acm.sdut.edu.cn/sdutoj/problem.php?action=showproblem&problemid=1012
#!/usr/bin/env python #coding:utf8 while True: line = raw_input() a=[] for x in line.split(): a.append(int(x)) if a[0]==0 and a[1]==0: break print sum(a)
5, A+B for Input-Output Practice (IV) : http://acm.sdut.edu.cn/sdutoj/problem.php?action=showproblem&problemid=1013
这段代码应该算是被我水过的,我是直接将这一行读取,然后所有的数相加,然后再减去 t (应该读入的数字的个数),并没有按照题目要求来,,呵呵,,先这样吧,
#!/usr/bin/env python #coding:utf8 while True: num=[] line = raw_input() for x in line.split(): num.append(int(x)) if num[0]==0: break a=num[0] print sum(num)-a
6, A+B for Input-Output Practice (V) : http://acm.sdut.edu.cn/sdutoj/problem.php?action=showproblem&problemid=1014
#!/usr/bin/env python #coding:utf8 t = int(raw_input()) while t>0: if t==0: break line = raw_input() num=[] for x in line.split(): num.append(int(x)) print sum(num)-num[0] t = t-1
7, A+B for Input-Output Practice (VI) : http://acm.sdut.edu.cn/sdutoj/problem.php?action=showproblem&problemid=1015
#!/usr/bin/env python #coding:utf8 while True: line = raw_input() num=[] for x in line.split(): num.append(int(x)) print sum(num)-num[0]
8, A+B for Input-Output Practice (VII) : http://acm.sdut.edu.cn/sdutoj/problem.php?action=showproblem&problemid=1016
被打败了,被'\r'打败了,,输出一个空行,,不解释
#!/usr/bin/env python #coding:utf8 while True: a=[] line = raw_input() for x in line.split(): a.append(int(x)) print sum(a) print '\r' #输出一个空行
附 : python转义字符:
在需要在字符中使用特殊字符时,python用反斜杠(\)转义字符。如下表:
转义字符 | 描述 |
---|---|
\(在行尾时) | 续行符 |
\\ | 反斜杠符号 |
\' | 单引号 |
\" | 双引号 |
\a | 响铃 |
\b | 退格(Backspace) |
\e | 转义 |
\000 | 空 |
\n | 换行 |
\v | 纵向制表符 |
\t | 横向制表符 |
\r | 回车 |
\f | 换页 |
\oyy | 八进制数yy代表的字符,例如:\o12代表换行 |
\xyy | 十进制数yy代表的字符,例如:\x0a代表换行 |
\other | 其它的字符以普通格式输出 |
#!/usr/bin/env python #coding:utf8 t = int(raw_input()) while t>0: line = raw_input() num = [] for x in line.split(): num.append(int(x)) print sum(num)-num[0] t = t-1 if t!=0: print '\r'
恩,,用python AC ,另一番风味。。。。
