我很难做到这一点。每次我运行查看照片按钮时，它只显示 python 脚本而不是应用程序本身。

我正在尝试运行下面的 Python 脚本：

from os.path import join, dirname, exists
from pymt import *
current_dir = dirname(__file__)
fontname_title=join(current_dir,'fonts','7.ttf')
fontname_author_desc=join(current_dir,'fonts','author_desc.ttf')

css='''
.desktop-background,
.desktop-coverflow {
draw-background: 1;
bg-color: #000000;
}
.desktop-author,
.desktop-description {
color: #999999;
}
.desktop-title {
font-size: 60;
}
'''


css_add_sheet(css)

class Desktop(MTBoxLayout):
layout_def = '''
<MTBoxLayout orientation='"vertical"' cls='"desktop-background"'>
    <MTCoverFlow size_hint='(1, .7)' cls='"desktop-coverflow"'
        thumbnail_size='(256, 256)' cover_distance='150' id='"coverflow"'/>
    <MTAnchorLayout size_hint='(1, .3)'>
        <MTBoxLayout cls='"form"' padding='20' orientation='"vertical"'>
            <MTLabel id='"title"' label='"Unknown Title"' autosize='True'
                cls='"desktop-title"' anchor_x='"center"'/>
            <MTLabel id='"author"' label='"Unknown Author"' autosize='True'
                cls='"desktop-author"' anchor_x='"center"'/>
            <MTLabel id='"description"' label='"Unknown Description"' autosize='True'
                cls='"desktop-description"' anchor_x='"center"'/>

使用下面的按钮

<html>
        <div class="art-blockcontent">
    <p style="text-align: center;"><img width="176" height="132" alt="" src="images/boat.jpg"></p>
<p style="text-align: center;">&nbsp;
<a href="Python\pictures\malacca.py" class="art-button">View Photo</a>&nbsp;<br></p></div>
</html>

由于您的 python 文件的 URL 中有反斜杠，我将猜测您做错了什么。

Python 不会在您的网络浏览器中运行。因此，如果您直接从硬盘加载 HTML 文件（即使用file://URL），那么浏览器将只显示您的源代码。

您需要设置一个 Web 服务器来运行 python。如何让服务器运行 python 代码取决于服务器。而且你可能想要重新编写你的 python 代码。它似乎是根据已被有效放弃多年的 CGI 标准编写的。每次请求页面时，CGI 都会运行一个程序，其中 HTML 被“打印”——因为它每次都会启动一个新进程，速度非常慢。现代系统加载代码一次，然后在每次请求页面时调用代码中的方法，该方法返回 HTML，或者更一般地说是包含 HTML 和元数据的“响应对象”。

我建议检查Flask或cherrypy作为简单的起点。
