从.txt解析Python字符串 [英] Python string parsing from .txt

问题描述

我有以下形式的字符串:

I have strings of the following form:

}# => 2[1 HMDB00001 ,2 HMDB00002]
}# => 5[1 HMDB00001 ,2 HMDB00002, 3 HMDB00003 ,4 HMDB00004,5 HMDB00005]
}# => 1[1 HMDB00001]

.p文件中的

.我正在尝试使用带有正则表达式的re.search()在python列表中解析它们，但到目前为止没有成功.如您所料，列表中应包含以下elements = ["1 HMDB00001", "2 HMDB00002", "3 HMDB00003"]元素.列表彼此独立.因此，解析时只能考虑(eg. }# => 2[1 HMDB00001 ,2 HMDB00002]).

in a .txt file. I am trying to parse them in python lists using the re.search() with regular expressions, but so far unsuccessful. As u can guess the list should contain elements as follows elements = ["1 HMDB00001", "2 HMDB00002", "3 HMDB00003"]. Lists are independent from each other. So, when parsing only one line can be taken in consideration (eg. }# => 2[1 HMDB00001 ,2 HMDB00002]).

推荐答案

这似乎有效，但是鉴于您的问题很难确定.您也许可以根据得到的答案拼凑出解决方案.

This seems to work, but its hard to tell for sure given your question. You may be able to piece together a solution from the answers you get.

import re

strings = [
    '}# => 2[1 HMDB00001 ,2 HMDB00002]',
    '}# => 5[1 HMDB00001 ,2 HMDB00002, 3 HMDB00003 ,4 HMDB00004,5 HMDB00005]',
    '}# => 1[1 HMDB00001]',
]

for s in strings:
    mat = re.search(r'\[(.*)\]', s)
    elements = map(str.strip, mat.group(1).split(','))
    print elements

哪个输出:

['1 HMDB00001', '2 HMDB00002']
['1 HMDB00001', '2 HMDB00002', '3 HMDB00003', '4 HMDB00004', '5 HMDB00005']
['1 HMDB00001']
