如何检查文本文件输入中的下一行

Question

在我的elif not块中，我需要检查文本文件的下一行，因为代码会继续检查相同的文件ID并卡在此部分中。文本文件提供了位于单独文件夹（FilesFolder）中的文件的所需位置和名称。这些文件需要移至现有的空树中，并位于正确的子目录中。

import os  

import os.path
import shutil
from pathlib import Path
data_folder = Path("C:/Users/Folder")
FilesFolder = Path("C:/Users/Files")
file_to_open = data_folder / "text.txt"
RootFolder = "TopFolder"
NewFolderTree = data_folder / RootFolder

with open(file_to_open) as f:
    #Striping the whitespace and extracting important parts.
    line = f.readline().strip()
    fold_location = line.split("~")[0]
    file_id = line.split("   ")[1]
    while line:
    # Iterating through files that need to be sorted.
    for file in os.listdir(FilesFolder):
    # Extracting the name, ignoring revision,extension(.zip,.pdf etc) and dashes.
    file_name = file.split('_')[0].split('-')[0].split('.')[0]
        for file_id in f: 
            if file_name == file_id:
    #  Check if the folder exists then copy the file to the corresponding folder in new tree.
                 for root, dirs, subdirs in os.walk(NewFolderTree):
                     if fold_location.exists():
                         dest = Path(fold_location)
                         # copy files occurs here
                     shutil.copy(file, dest)
                     elif not subdir.exists():
                         print("Folder does not exist for " + fold_location)

             elif not file_name == file_id:
             # how do I check the next line from text file?


             # gets to end of text file.
             else: 
                 print('The following document is missing ' + file_name )
