appending variabl a URL for requests.post step

[duckredbeard]

I use one of my RPis for monitoring my fridge temp. I currently have LEDs lit to indicate a good or bad condition. I also get a push notification when the monitoring service starts (cronjob @reboot). The code is a loop that checks the temps every 5 minutes and will send me a push notification (using requests.post and Android apps Join and Tasker). Using Tasker, I can have my phone respond to incoming messages (not just text messages - think pushes). I want the pi to attach a variable to the base of the URL so I can catch the event, where Tasker can alert me, showing the issue.

import requests


base = https://autoremotejoaomgcd.appspot.com/sendmessagekey=goo.gl:lonstrinofcharactersthatyoudonotneedforthis&message=

alert = overtempfreezer

r = requests.post("base + alert")

So the "base" variable will always be that. Never changes. It has been edited for privacy. At the end is "&message=" where the next characters would be the "alert" variable. I am hoping to combine the ougoing requests.post to be "https://autoremotejoaomgcd.appspot.com/sendmessagekey=goo.gl:lonstrinofcharactersthatyoudonotneedforthis&message=overtempfreezer"

Why not just combine them? There are other conditions that could be populated to be the "alert" variable, such as alert = overtempfridge, or alert = freezerdooropen.

How do I append the "alert" variable to the "base" and send it with a requests.post?
