完全正确的啊,难道是传说中的RPWT作者: darkboy 时间: 2007-10-23 16:28
汗！不是吧？
我输入quit后回车，仍旧提示我输入，下面是我控制台内容：
Enter something : quit
Length of the string is 5
Enter something :
郁闷！我用的是eclipse+Pydev 作者: rubee 时间: 2007-10-23 16:36
s=eval(raw_input('Enter something : '))看看这个可以不作者: JarLing 时间: 2007-10-23 16:38
是不是多输了一个空格？
用s.strip()去除空格看看作者: darkboy 时间: 2007-10-23 16:40
4楼的会出错，当我输入a,控制台的错误如下：
Enter something : a
Traceback (most recent call last):
File "D:\work32\yp\src\break.py", line 5, in <module>
s =eval(raw_input('Enter something : '))
File "<string>", line 1
a

应该不是5楼说的空格的问题，我用了s.strip()，问题仍旧存在，大家难道输入quit可以执行“Done”?作者: happygg 时间: 2007-10-23 17:05
>pythonw -u "test.py"
Enter something : 11
Length of the string is 2
Enter something : quit
Done
>Exit code: 0
运行了楼主程序，没有问题作者: darkboy 时间: 2007-10-23 17:12
我在eclipse +Pydev里面运行才出现上面的一些问题，而且输入一个a,显示的字符串长度是2，如下：
Enter something : a
Length of the string is 2
Enter something :
Nope, this is a python bug mixed with a bad specification on how a shell is supposed to behave.
Usually shells put a '\n' when you press enter, but the Eclipse console puts '\r\n' and python does not handle it well, as this is not specified anywhere, and does not seem such awkward, my feeling is that it's a python bug, but you can surely argue the other way... so, you can submit a bug to eclipse.org and python.org and see who'll fix it... (or you can handle it in your program).
while True:
s=raw_input('Enter something:')
s.strip()
print repr(s)
if s=='quit':
break
print 'Length of the string is', len(s)
print 'Done'
控制台显示：
Enter something:4
'4\r'
Length of the string is 2

s=s.strip()......作者: darkboy 时间: 2007-10-24 10:04
s=s.strip()就ok
几个疑点都弄清楚了，谢谢大家
