import logging

import azure.functions as func


def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    isValid = True
    try:
        req_body = req.get_json()
        p = req_body['principal']
        t = req_body['time']
        r = req_body['rate']
        si = p * t * r /100
    except ValueError:
        isValid = False


    if isValid:
        return func.HttpResponse(f"Simple Intrest is {si}")
    else:
        return func.HttpResponse(
             "Ensure you send a json body with principal time and rate",
             status_code=200
        )
