How to display a variable in HTML
提问by Ricky92d
I am making a web app using Python and have a variable that I want to display on an HTML page. How can I go about doing so? Would using {% VariableName %}in the HTML page be the right approach to this?
我正在使用 Python 制作一个网络应用程序，并且有一个我想在 HTML 页面上显示的变量。我该怎么做？将使用{% VariableName %}在HTML页面是正确的做法呢？

This is very clearly explained in the Flask documentationso I recommend that you read it for a full understanding, but here is a very simple example of rendering template variables.
这在 Flask文档中有非常清楚的解释，所以我建议你阅读它以充分理解，但这里有一个非常简单的渲染模板变量的例子。
HTML template file stored in templates/index.html:
HTML 模板文件存储在templates/index.html：
<html>
<body>
<p>Here is my variable: {{ variable }}</p>
</body>
</html>
And the simple Flask app:
以及简单的 Flask 应用程序：
from flask import Flask, render_template
app = Flask('testapp')
@app.route('/')
def index():
return render_template('index.html', variable='12345')
if __name__ == '__main__':
app.run()
Run this script and visit http://127.0.0.1:5000/in your browser. You should see the value of variablerendered as 12345
运行此脚本并在浏览器中访问http://127.0.0.1:5000/。你应该看到variable渲染的值12345
