Python is a server-side language. Python是一种服务器端语言。 This means it cannot be executed via a webpage directly, as it runs on a server (hidden from user visibility.) You must declare python code in .py files. 这意味着它不能直接通过网页执行，因为它在服务器上运行（对用户可见）。您必须在.py文件中声明python代码。 Your HTML code could submit elements to a cgi end point, for example, which then allows the python to digest and return values: www.tutorialspoint.com/python/python_cgi_programming.htm 例如，您的HTML代码可以将元素提交到cgi端点，然后该端点允许python消化并返回值：www.tutorialspoint.com/python/python_cgi_programming.htm
