对于这个文件，其中一个文件中可能存在间距差异或一些Unicode字符，这可能会导致您出现问题。
我有一个python脚本，它给了我两个文件之间的区别，希望这对你有帮助。

import csv

def main():
    old_file = 'oldfile.txt'
    new_file = 'newfile.txt'

    # Create sets to store the unique values from each file
    old_set = set()
    new_set = set()

    # Open the old file and add the first column of each row to the old_set
    with open(old_file, 'r') as f:
        reader = csv.reader(f)
        for row in reader:
            old_set.add(row)

    # Open the new file and add the first column of each row to the new_set
    with open(new_file, 'r') as f:
        reader = csv.reader(f)
        for row in reader:
            new_set.add(row)

    
    # Print the missing values
    print(missing_values)

if __name__ == "__main__":
    main()

如果你没有看到任何打印出来的东西，试着颠倒文件名，这可能是一种方式或其他。希望这能有所帮助
