如何从下一个代码的html页面上的flask中的python代码中获取数据

我试图通过Flask从HTML页面上的“byp”和“yp1”获取数据，但我做不到

以及我想打印在html页面都打印内容

我试图定义一个新的路由页面，并通过使用像{{byp}和{{{yp1}}这样的Jinja命令导入，但并没有起作用。我在该领域是新手，我确信之前有一些事情要做

代码100%有效

谁能给我一个提示吗

    import requests, json
    import datetime
    import time

@app.route('/bpay/' + token_urlsafe(12))
def getBitcoinPrice():
    URL = 'https://www.bitstamp.net/api/ticker/'
    try:
        r = requests.get(URL)
        priceFloat = float(json.loads(r.text)['last'])
        bp = getBitcoinPrice()
        yp = 12
        byp = yp / bp
        yp1 = bp * byp
        btc = '1F1tAaz5x1HUXrCNLbtMDqcw6o5GNn4xqX'

        return render_template('a/bpay.html', byp=byp, yp1=yp1, bp=bp)

    except requests.ConnectionError:
        print ('Error querying Bitstamp API')

因此，我尝试了以下代码：

URL = os.popen("GET https://www.bitstamp.net/api/ticker/").read()
    for last in URL:
        r = requests.get(URL)
        pf = float(json.loads(r.text)['last'])
    bp = pf
    yp = 12
    byp = yp / bp
    yp1 = bp * byp

我得到了这个错误：

过去几个月我一直在练习烧瓶。我希望这能对你有所帮助。我试着让它简单易懂，因为你是新手

使用render_template将路由功能与html模板连接（确保html模板位于templates目录中

后端

在Jinja模板中，打印来自后端的变量

谢谢，但我喜欢这样，但它不起作用：（@alex用您尝试过的代码更新问题。在您这样做之前，我们无法知道什么不起作用。@BhushanBabar的想法是，我正在尝试Masud Rumir在其示例中的做法，但不起作用。数据没有出现，更甚者，没有错误……请检查python代码中的正确缩进。我的代码中的缩进可能不正确示例代码。应该可以使用。@alex的示例没有经过您的修改就可以使用了吗？您好，您可以使用吗？@BhushanBabar没有使用，我不知道如何使用，或者缺少了一些内容。我在互联网上找到了很多与json相关的资料，在我的水平上，这些资料现在不容易理解：（.我正在寻找一种替代方法来添加价值观手册，而不是更新它们，这对我很有帮助，但不是我所期望的……也许我想的比我的知识还多。。。

from flask import Flask, render_template

app = Flask(__name__)

@app.route('/test')

    text = 'Hello World'
    return render_template('test.html', text=text)

if __name__ == '__main__':
    app.jinja_env.auto_reload = True
    app.config['TEMPLATES_AUTO_RELOAD'] = True
    app.debug = True
    app.run(host='0.0.0.0', port=5000)

{{ text }}
