例如,pathvalidate库可以方便地检查路径是否合法,并对不合法的路径进行修正。 下面是一个使用pathvalidate库的示例代码: frompathvalidateimportsanitize_filepath,sanitize_filename# 检查文件路径file_path="/path/with/invalid?characters.txt"sanitized_path=sanitize_filepath(file_path)print(f"Sanitized file path:{...
with open(file_path, 'r') as file: data = validate_data(file.read()) except FileNotFoundError: print(f"文件 {file_path} 未找到!") except InvalidDataError: print(f"文件 {file_path} 中的数据格式有误!") else: process_valid_data(data) print(f"文件 {file_path} 的数据已成功读取并验...

如果我们正在开发一个Web应用,我们可以使用HTML表单的min和max属性,以及JavaScript或后端语言(如Python的Flask或Django)进行输入验证。 defvalidate_number_from_file(file_path, min_value, max_value):withopen(file_path,'r')asfile:forlineinfile: number =int(line.strip())# 假设每行只有一个整数,且没有额...
当运行python/path/to/directory/时,Python 的行为就像我们输入python/path/to/directory/__main__.py一样。 换句话说,Python 会做以下两件事: 将目录/path/to/directory/添加到模块路径中。 执行/path/to/directory/__main__.py中的代码。 运行python /path/to/filename.zip时,Python 会把文件当做一个目录...
