Question

Im writting this code to get some values of stock prices, and how can I render output results in results.html page? I'm using Heroku to make this app.

import cota
print('-----INDICADOR EURO COMERCIAL H1----')

Thanks for your attention.

Answer 1

I hope I can be helpful, and I don't know much about Python. But it sounds like if you're doing Server-side rendering of the html page, you just need a template engine such as Jade, Pug, or something of that sort.

Answer 2

Here are some examples for you to follow:

https://www.grizzlypeaksoftware.com/articles?id=1m3W3llyJLy4YS5OpyyxBq

https://scotch.io/tutorials/getting-started-with-flask-a-python-microframework

https://scoutapm.com/blog/python-flask-tutorial-getting-started-with-flask

https://www.liquidweb.com/kb/getting-started-with-flask/

https://github.com/akibrhast/flask_base_template

Basically what you need to learn about is how to create a backend server. In this case using flask. The templating engine that is typically used with flask is called Jinja. Once you make your request call to your data you would want to pass it through to your routes via jinja.

Here is a basic example:

from flask import Flask, flash, redirect, render_template, request, session, abort,url_for
import os

#from flask_login import login_user, current_user, logout_user, login_required #Optional login imports, need to 'pip install flask_login'

app = Flask(__name__)

@app.route('/')
def index():
  return render_template("base.html")

if __name__ == '__main__':
    app.secret_key = os.urandom(12)
    app.run(debug=True)

I solved the problem: Here is the solution I've found:

First, you can visit the app here: finance-python.herokuapp.com
