匹配 2 个文本文件中的文本并从第一个文件获取信息并附加到另一个文件

Question

我有 2 个文本文件。第一个文件包含文本的元数据信息（如字体大小等），第二个文件仅包含文本。我需要匹配两个文件之间的文本，从第一个文件中获取元数据信息并将其添加到第二个文件中。例如，文件A数据：[Base Font : PSJEPX+Muli-Light, Font Size : 7.5, Font Weight : 300.0]We are not satisfied with our 2018 results. We have the global footprint, assets and team to [Base Font : SVTVFR+Muli-Light, Font Size : 7.5, Font Weight : 300.0] [Base Font : PSJEPX+Muli-Light, Font Size : 7.5, Font Weight : 300.0]perform better. We have made a number of changes to position for sustainable growth.New line that does not start with square brackets.[Base Font : SVTVFR+Muli-SemiBold, Font Size : 8.1, Font Weight : 600.0]Innovation文件 B 数据：We are not satisfied with our 2018 results. We have the global footprint, assets and team to perform better. We have made a number of changes to position for sustainable growth.New line that does not start with square brackets.Innovation预期输出：[Base Font : PSJEPX+Muli-Light, Font Size : 7.5, Font Weight : 300.0]We are not satisfied with our 2018 results. We have the global footprint, assets and team to perform better. We have made a number of changes to position for sustainable growth.New line that does not start with square brackets.[Base Font : SVTVFR+Muli-SemiBold, Font Size : 8.1, Font Weight : 600.0]Innovation因此，基本上，只有当元数据信息发生更改时，“文件 A”中的元数据才必须附加到“文件 B”。我的方法： def readB(x):     with open(File B) as resultFile:         for line in resultFile:             if x in line:                 print(x)def readA():    with open(File A) as bondNumberFile:        for line in bondNumberFile:            readB(line)readA()我的问题是，我不确定如何从文件 A 中获取元数据信息并将其附加到文件 B。此外，我的代码在匹配文本时无法处理元数据信息（方括号内）。

Answer 1

请尝试下面的程序。该程序首先读取filea并创建样式和线条的字典，然后逐行读取fileb以从字典中匹配和选择样式，并将其写入到filec.

import re

table={}

with open("filea.txt","r") as f:

    for line in f:

        if line.strip():

            parts=re.findall("^(\[.*?\])?(.*)$",line)[0]

            if parts[0] in table:

                table[parts[0]]+=parts[1]

            else:

                table[parts[0]]=parts[1]

with open("fileb.txt","r") as f, open("filec.txt","w") as f1:

    for line in f:

        if line.strip():

            for i in table:

                if line.strip() in table[i]:

                    f1.write(i+line)

                    break

                else:

                    pass

        else:

            f1.write(line)

输出

[Base Font : PSJEPX+Muli-Light, Font Size : 7.5, Font Weight : 300.0]We are not satisfied with our 2018 results. We have the global footprint, assets and team to perform better. We have made a number of changes to position for sustainable growth.

New line that does not start with square brackets.
