我要说的是:
string= { id : 1 }
并且现在使用Perl/sed的护卫,我想得到一些东西。
string=id

请让我略感了解一下,在座各位如何做到这一点? 我预计reg子会类似,但我不敢肯定 p子和我应该使用什么进口品,I m在沙尔开端: 感谢您:

在沙里,你经常使用<代码>re模块。 我对你的定期表述作了修改,但总体来说,这就是如何经常用字眼替换表达方式:
>>> import re
>>> s = "{ id : 1 }"
>>> re.sub(r"{ ([^ ]*) .*$", r 1 , string)
id
The sub()
function accepts the regex first, then the replacement and finally the string. The documentation of the re module has some more information:
http://docs.python.org/library/re.html
The r
prefixing to the strings adopted as debate basic notess 用来将他们视为“草”扼杀物,在这种地方,大多数反弹越狱事件没有解释。
首先,我同意@PenguinCoder:由于这是有效的初等人物,你应当真正思考如何仅仅利用斯图尔为处理JSON提供支持。
我去了谷歌,在关键词中打上了字:Python 常规表述
。
这里是头两点:

如果你们读了这些话,你将找到答案。
这里的工作守则:
import re
s = string= "{ id : 1 }"
pat = re.compile(r"s*([^=]+)s*=[s "]*{s* ([^ ]+) ")
m = pat.match(s)
if m is not None:
id = m.group(1)
name = m.group(2)
result = "%s=%s" % (id, name)
# note: could also do this: result = "%s=%s" % m.groups()
