比较两个文本文件，找出列表中的差异，并找出哪些列表值不匹配

def compare_text_files(file1, file2):
    # 读取文件内容并存储在列表中
    with open(file1, 'r') as f1:
        list1 = f1.readlines()
    with open(file2, 'r') as f2:
        list2 = f2.readlines()

    # 确定较长的列表作为基准
    if len(list1) >= len(list2):
        base_list = list1
        compare_list = list2
    else:
        base_list = list2
        compare_list = list1

    differences = []  # 存储差异的值
    mismatched_positions = []  # 存储不匹配的位置

    # 遍历基准列表，逐个比较对应位置的值
    for i in range(len(base_list)):
        if i >= len(compare_list):  # 比较列表长度不足时跳出循环
            break
        if base_list[i] != compare_list[i]:
            differences.append(base_list[i])
            mismatched_positions.append(i)

    return differences, mismatched_positions

# 示例用法
file1 = 'file1.txt'
file2 = 'file2.txt'
differences, mismatched_positions = compare_text_files(file1, file2)

print("差异的值：")
for diff in differences:
    print(diff)

print("不匹配的位置：")
for pos in mismatched_positions:
    print(pos)
