如何在 AWS EC2 上运行 python 代码然后使用 POST？

Question

lets say I have this code

s =int(input("Input a number "))

x = s+5 

print(x)

how do I run it on EC2 and then use flask to get the output using POST so I can use it on a front end?

I want to make a webpage where a user can input s and then the backend which is an index.py file that communicates with AWS EC2 (using flask) to run the python code above and then return the value x to the front end

flask app sample code

#!/usr/bin/python
from flask import Flask, request, jsonify
from index import some_fun

app = Flask(_name_)


@app.route('/foo', methods=['POST'])
def foo():
    data = request.form.to_dict()
    function_response = some_fun(data['form_field'])
    print(function_response)
    return jsonify(data)

if __name__ == "__main__":
    app.run()

You python script, index.py from where you want call some_function

def some_fun(x): return x + 5

here i have considered post request is of multipart/form-data. if you are making post request with application/json then

data = request.json
