python3怎么用re导出文本数据-创新互联
小编给大家分享一下python3怎么用re导出文本数据,相信大部分人都还不怎么了解,因此分享这篇文章给大家参考一下,希望大家阅读完这篇文章后大有收获,下面让我们一起去了解一下吧!

文本内容如下,就是一个编译后的map,我想提取里面的symbol信息,地址,以及在哪些模块里面使用了
当下面有多行时,也就是在多个.o文件中使用时,怎么提取出每一个.o
表达式是:
_([a-zA-Z0-9_]+)\s+([a-z0-9A-Z]{8})\s+defined\s+in\s+[a-zA-Z0-9_]+.o\s+section\s+.+\n\s+used in\s+([a-zA-Z0-9_]+.o)\s*\n\s*(\w+.o)\n\s*(\w+.o)问题1:
当需要匹配多个“ ******.o”时如何匹配
问题2:
如何把所有满足条件的都匹配出来,
_PfTORQ_r_ThermEffCorrMult 000fe417 defined in torqmall.o section .bss used in torqmctl.o torqmrat.o _PeTORQ_GearState 000fe419 defined in torqmall.o section .bss used in torq_meth_jac.o torq_mulf_jac.o torqmgve.o torqmgvv.o etcdmtps.o _PeTORQ_GearStatePrev 000fe41a defined in torqmall.o section .bss _PeTORQ_GearStateDsrd 000fe41b defined in torqmall.o section .bss _VfTORQ_AXIS_RPM_W_11Brk 000fe41c defined in torqmall.o section .bss used in torqmdes.o tqdrmall.o
解决方法:
re.findall(pattern, string, flags=0)
范例:
>>> text = "He was carefully disguised but captured quickly by police." >>> re.findall(r"\w+ly", text) ['carefully', 'quickly']
测试:
In [1]: yourstr="""_PfTORQ_r_ThermEffCorrMult 000fe417 defined in torqmall.o section .bss
used in torqmctl.o
torqmrat.o
_PeTORQ_GearState 000fe419 defined in torqmall.o section .bss
used in torq_meth_jac.o
torq_mulf_jac.o
torqmgve.o
torqmgvv.o
etcdmtps.o
_PeTORQ_GearStatePrev 000fe41a defined in torqmall.o section .bss
_PeTORQ_GearStateDsrd 000fe41b defined in torqmall.o section .bss
_VfTORQ_AXIS_RPM_W_11Brk 000fe41c defined in torqmall.o section .bss
used in torqmdes.o
tqdrmall.o"""
In [2]: re.findall('\w+\.o',yourstr)
Out[2]:
['torqmall.o',
'torqmctl.o',
'torqmrat.o',
'torqmall.o',
'torq_meth_jac.o',
'torq_mulf_jac.o',
'torqmgve.o',
'torqmgvv.o',
'etcdmtps.o',
'torqmall.o',
'torqmall.o',
'torqmall.o',
'torqmdes.o',
'tqdrmall.o']以上是python3怎么用re导出文本数据的所有内容,感谢各位的阅读!相信大家都有了一定的了解,希望分享的内容对大家有所帮助,如果还想学习更多知识,欢迎关注创新互联行业资讯频道!
