"在 HTML \/ .format() 中使用 Python 变量"
[英]Using Python Variable in HTML / .format()
问题描述
I am having a really hard time getting the "marker" to show up.
我很难让“标记”出现。 I do not know how to use .format() correctly to show the marker inside the string.我不知道如何正确使用.format()来显示字符串内的标记。
Does the variable need to be in a specific location in the string?变量是否需要位于字符串中的特定位置？ Trying to get a grasp of this for the first time.第一次尝试掌握这一点。 Sorry if I am asking basic questions.对不起，如果我问的是基本问题。
Keep getting : """.format(marker) KeyError: 'font-family' . Not sure where the problem is.不断得到： """.format(marker) KeyError: 'font-family' 。不确定问题出在哪里。
marker = "AUniqueMarker"
# Create the body of the message (a plain-text and an HTML version).
text = "This is a test message.\nText and html."
html = """\

You need to escape the presence of other curly braces ( { and } ) in the string, otherwise the string will be misinterpreted by format . 您需要转义字符串中其他花括号（ {和} ）的出现，否则该字符串将被format误解。
You have to repeat the characters to escape them. 您必须重复字符才能转义它们。 In the string you are calling format on, change the line 在您调用format的字符串中，更改行
{mso-style-name:"Table Normal";
to 至
{{mso-style-name:"Table Normal";
and similarly for the closing bracket. 和类似的结束括号。

You must double the { and } in your string, otherwise format will try to interpret text between braces. 您必须将字符串中的{和}加倍，否则format会尝试解释大括号之间的文本。
您可以使用replace来做到这一点： html = """\
your html code
""".replace("{", "{{").replace("}", "}}").format(marker=marker)
EDIT : replace will transform {marker} into {{marker}} , so it will not be interpreted by format ... 编辑： replace将{marker}转换为{{marker}} ，因此它不会被format解释...

If you don't want to manipulate the HTML code and add extra {} or %, python's Template<\/strong> string might be exactly what you're looking for.如果您不想操作 HTML 代码并添加额外的 {} 或 %，python 的模板<\/strong>字符串可能正是您要寻找的。 Let's take a look at an example:我们来看一个例子：
from string import Template
t = Template('<body> $marker </body>')
t.substitute(marker='Hello World!')
'<body> Hello World! </body>'
