我有一个这样的文件：

我希望能够搜索此文件并提取括号内的所有数据并将其生成为如下输出：

0000NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN0DNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN0NNNNNNNNNNNNNNNNN0NN00N00NN0NNNNNNNNNNNNNN
0000NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN0DNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN0NNNNNNNNNNNNNNNNN0NN00N00NN0NNNNNNNNNNNNNN

到目前为止我试过了，但没有成功：

import re
from pathlib import Path
with open ("results.txt", "r") as myfile:
    data=myfile.readlines()
ctr=0
for i in data:
    m = re.search(r"\[([A-Za-z0-9_]+)\]", str(i))
    print(m)

非常感谢任何意见！

Answer 1

你已经有了答案

import re
from pathlib import Path
with open ("results.txt", "r") as myfile:
    data=myfile.readlines()
ctr=0
for i in data:
    m = re.search(r"\[([A-Za-z0-9_]+)\]", str(i))
    if m:
        # print only the first match
        print(m[0][1:-1])
        print(m.groups[0])

help(m.groups)
"""
Help on built-in function groups:

groups(default=None) method of re.Match instance
    Return a tuple containing all the subgroups of the match, from 1.
    
    default
      Is used for groups that did not participate in the match.
"""

Answer 2

试试这个：-

import re

with open('results.txt') as infile:
    for line in infile:
        m = re.search(r'.*?\[(.*)].*', line)
        if m:
            print(m.group(1))
