使用.format将文本插入到某些HTML代码中，获取错误（Python）

I'm pretty new to Python, and for practice I decided to create a little program to help my dad update his website (he owns a small movie theater) to show what movies are playing.

我对Python很陌生,为了练习,我决定创建一个小程序来帮助我爸爸更新他的网站(他拥有一个小电影院)来显示正在播放的电影。

I basically made a bunch of text boxes to enter the movie's title, cast, times playing, etc. When you're done, hit "Submit" and it spits out a new index.html page to upload to the server.

我基本上制作了一堆文本框来输入电影的标题,演员表,播放时间等等。完成后,点击“提交”,它会吐出一个新的index.html页面上传到服务器。

The problem is, I'm using {0}, {1}, {2} etc. to insert the new information from the textboxes into the HTML code (which is a string in my program), and Python keeps getting confused because the HTML code has some Javascript with curly braces in it.

问题是,我正在使用{0},{1},{2}等将文本框中的新信息插入到HTML代码中(这是我程序中的一个字符串),并且Python不断混淆,因为HTML代码中包含一些带花括号的Javascript。

Here's the code:

这是代码:

    def submit(self):
        self.createHTML(('''<lots of html>{some javascript stuff}{0}{1}{2}{3}{4}{5}{6}{7}
'''.format((self.text_title.get(1.0,'end')),
           (self.text_date2d.get(1.0,'end')),
           (self.text_date3d.get(1.0,'end')),
           (self.text_cast.get(1.0,'end')),
           (self.text_summary.get(1.0,'end')),
           (self.text_runtime.get(1.0,'end')),
           (self.text_trailer.get(1.0,'end')),
           (self.text_image.get(1.0,'end'))))) 

I replaced the HTML with <lots of html>{some javascript stuff} to make it simpler here on stack (and to help get to the root of the problem).

我用 {some javascript stuff}替换了HTML,使其在堆栈上变得更简单(并帮助找到问题的根源)。

When I have the actual site's HTML code in my program, it says "ValueError: unexpected '{' in field name" and points to the end of the function (self.text_image.get(1.0,'end'))))). When I use the simplified version above, I get "KeyError: 'some javascript stuff'", and it also points to the end of the function.

当我在我的程序中有实际站点的HTML代码时,它会显示“ValueError:unexpected'{'in field name”并指向函数的结尾(self.text_image.get(1.0,'end'))))) 。当我使用上面的简化版本时,我得到“KeyError:'一些javascript的东西'”,它也指向函数的结尾。

I think it might work if I can tell Python to ignore all the JavaScript curly braces, but using escape characters isn't working.

我认为如果我可以告诉Python忽略所有的JavaScript花括号,它可能会有效,但是使用转义字符是行不通的。

Hopefully this made sense. Can anyone help?

希望这是有道理的。有人可以帮忙吗?

It looks like you need to escape your curly braces in the JavaScript portion. You can do by using the double curly braces {{ }} instead of single curly braces in your JavaScript.

看起来你需要在JavaScript部分中转义花括号。您可以在JavaScript中使用双花括号{{}}而不是单个花括号。
