I have a simple example of my problem, I cannot get a python script/function result to be sent to Flask HTML when the script is being ran. I have tried everything I saw here on SO, I'm sure it's possible, but I have been stuck for a while. Here is just a simple example of what I cannot get working.
Flask Code:
from flask import Flask, render_template
import time
app = Flask(__name__)
def mycounter():
for x in range(0, 10):
print(f"<p> {x} </p>")
time.sleep(1)
@app.route("/")
@app.route("/index")
def index():
return render_template('index.html', output=mycounter())
if __name__ == "__main__":
app.run(port=80, debug=True)
HTML Code:
<!DOCTYPE html>
<html>
<head>
<title>Title</title>
</head>
<body>
<p>{{ output }}</p>
</body>
</html>
All I want this to do is count from 0 to 9 every second and print to HTML every second rather than the console. I have tried popen but perhaps I am using it wrong? Thank You!

Instead of printing you should return values I guess:
def mycounter():
test=[]
for x in range(0, 10):
time.sleep(1)
test.append(x)
return test
