'''是怎么用的？求教！
>>> pystr = '''python 
... is cool''' 
>>> pystr 
'python\nis cool' 
>>> print pystr 
python 
is cool

[解决办法]
'''三引号一般用来定义多行字符串,从'''开始,直到碰到'''结束,中间所有字符(包括换行)都是字符串内容,无需转义字符

看测试

Python code

>>> s = '''this is a testof multiline string, includingspecial characters like *,',",\,/,...,!,`,etc.even 中文字符 is acceptable.'''>>> s'this is a test\nof multiline string, including\nspecial characters like *,\',",\n\\,/,...,!,`,etc.\neven \xd6\xd0\xce\xc4\xd7\xd6\xb7\xfb is acceptable.\n'>>> print sthis is a testof multiline string, includingspecial characters like *,',",\,/,...,!,`,etc.even 中文字符 is acceptable.>>>

你会发现,在三引号表示的字符串中,特殊字符会被自动转义,非常好使
