I am using Flask for my backend and brython for my client side since I need to use python modules that aren't available for javascript. At the moment, I am having trouble with importing modules from different folders. For instance, suppose I wanted to import test.py in brython. My file directory is as follows:
root
-- app.py
- templates
-- index.html
-- test.py
I have also tried putting test.py into the root directory along with an __init__.py file, but with no luck. The example code is to follow.
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<title>{{ title }}</title>
</head>
<body onload="brython()">
<h3>Testing Brython with Flask</h3>
<div id="test">

<script type="text/python">
from browser import document
import test
value = test.do_math(4,6)
output = 'my number is '+(str(value))
document['test'] <= output
</script>
</body>
</html>
test.py
def do_math(m,n):
return m+n
app.py
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def home():
title="Home"
return render_template("index.html", title=title)
if __name__=='__main__':
app.run(debug=True)
You need to do the import in your app.py.
And in your html file, you can just take that value.
