我有 2 個文本文件。第一個文件包含文本的元數據信息（如字體大小等），第二個文件僅包含文本。我需要匹配兩個文件之間的文本，從第一個文件中獲取元數據信息并將其添加到第二個文件中。例如，文件A數據：[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 數據：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預期輸出：[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，只有當元數據信息發生更改時，“文件 A”中的元數據才必須附加到“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()我的問題是，我不確定如何從文件 A 中獲取元數據信息并將其附加到文件 B。此外，我的代碼在匹配文本時無法處理元數據信息（方括號內）。

請嘗試下面的程序。該程序首先讀取filea并創建樣式和線條的字典，然后逐行讀取fileb以從字典中匹配和選擇樣式，并將其寫入到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)
輸出

New line that does not start with square brackets.
