如何在Python中删除字符串末尾带有特殊字符的行

def remove_special_lines(file_path, special_chars):
    # 读取文件
    with open(file_path, 'r') as file:
        lines = file.readlines()

    # 删除特殊字符
    modified_lines = []
    for line in lines:
        modified_line = line.rstrip(special_chars)
        modified_lines.append(modified_line)

    # 重新写入文件
    with open(file_path, 'w') as file:
        file.writelines(modified_lines)

# 调用示例
file_path = 'example.txt'  # 替换为你的文件路径
special_chars = '\n'  # 替换为你要删除的特殊字符，例如换行符
remove_special_lines(file_path, special_chars)
