Python CGI-标头之前的脚本输出结束

Question

I've created a simple script that reads an HTML-file and parses some variables on it. 我创建了一个简单的脚本，该脚本读取HTML文件并解析其中的一些变量。 Then it creates a new file and writes the HTML-code to it. 然后，它创建一个新文件并向其中写入HTML代码。 After that, it should redirect you to the newly created file. 之后，它应该将您重定向到新创建的文件。 But I am getting this error: End of script output before headers. 但是我遇到了这个错误：标头之前的脚本输出结束。

This is my Python code: 这是我的Python代码：

#!C:\Program Files\Python36\python.exe

import cgi, urllib.request

data = cgi.FieldStorage()

def varordef(name, default):
   return default if data.get(name) == None else data.get(name)

page_title = varordef('page_title', 'Example CGI')

with urllib.request.urlopen('homepage.thtml') as response:
   html = response.read() % (page_title)
   file = open('homepage.html', 'w')
   file.write(html)

print('Content-type: text/html\n\r') # I've already tried removing this line, but that gives me the same error
                                     # And I also tried putting this line on the top, but then I just get a blank page and it doesn't redirect you
                                     # Also, I tried to put both of those headers on the top, and then it redirects me to the specified URL, but the code below wasn't executed and it didn't create the file, so I get a 404


print('Location: homepage.html\n\r')

HTML-file: HTML档案：

<html>
<head>
    <title>{0}</title>
    <link rel='stylesheet' type='text/css' href=''>
</head>
<body>
    <form action='getfullname.py' method='get'>
        <p id='box-first_name'>
            Please enter your first name:
            <input type='text' id='first_name'>
        </p>
        <p id='box-last_name'>
            Please enter your last name:
            <input type='text' id='last_name'>
        </p>
        <p id='box-full_name'>
            This is your full name:
            <input type='text' id='full_name' disabled>
        </p>
        <p id='box-submit'>
            <input type='submit' id='submit'>
        </p>
    </form>
</body>
</html>
