Pass Variable from python (flask) to HTML in render template?
提问by ThePGT
The web server works (python flask) but when I go to the website, where the value of animal should be (dog) it shows the variable name animal. (There is more to the code but this is the most simplistic version which is the same concept.
Web服务器工作（python烧瓶）但是当我访问网站时，animal的值应该是（dog）它显示了变量名animal。（代码还有更多，但这是同一个概念的最简单版本。
Let's say I have these lines of code in my python script running python flask.
假设我在运行 python flask 的 python 脚本中有这些代码行。
animal = dog
return render_template('index.html', value=animal)
and in my HTML
在我的 HTML 中
<h3>I like the animal: {{ value }}<h3>
but rather than displaying 'dog' it displays the variable name 'animal'. So how would I go about displaying the Python variable to HTML? Thank you
但不是显示“狗”，而是显示变量名称“动物”。那么我将如何将 Python 变量显示为 HTML？谢谢

Shouldn't it be animal = 'dog'? If 'dog' is the value you want to see printed after "I like the animal:", this is what you need to do:
不应该animal = 'dog'吗？如果 'dog' 是你想在“I like the Animal:”之后看到的值，这就是你需要做的：
animal = 'dog'
return render_template('index.html', value=animal)

As you have to pass a value using a variable you have to define it as a string like:
animal = 'dog'then pass it to the html template:
return render_template('index.html', value=animal)
由于您必须使用变量传递值，因此您必须将其定义为字符串，例如：
animal = 'dog'然后将其传递给 html 模板：
return render_template('index.html', value=animal)
Now, you should see the passed value in the HTML.
现在，您应该会在 HTML 中看到传递的值。
