Need help creating a loop - codingnewbie - Jul-17-2019

Hey everyone so I need help creating a loop, Im trying to get temperature with 2 DS18B20 temperature sensors with a Raspberry Pi. So far I have managed to read a display temperature but only once, Ive been trying to turn it into a loop however I have no clue where to even start. Ill post the code Im using below, hopefully someone can help.

import os
import glob
import time
import datetime
import RPi.GPIO as iO
import os,subprocess
from subprocess import call
from w1thermsensor import W1ThermSensor
from Adafruit_IO import *

aio = Client(x,x')#UserID and KEY


os.system('modprobe w1-gpio')
os.system('modprobe w1-therm')
 

mySensor = W1ThermSensor()

# -------------------------------------
# Define sensors by ID

sensorID_Case = "00000a99ccc8"
sensorID_Shed = "000009171ec6"

for mySensor in W1ThermSensor.get_available_sensors():
	curSensorID = mySensor.id
	curTemp = mySensor.get_temperature()
	curTemp = round(curTemp,1)
	
	if curSensorID == sensorID_Case:
		myTempCase = curTemp
		print("Top=" + str(myTempCase*1.8+32))
	elif curSensorID == sensorID_Shed:
		myTempShed = curTemp
		print("Bottom=" + str(myTempShed*1.8+32))
	else:
		print("Unexpected SensorID=" + curSensorID)
	myTimeStamp = datetime.datetime.now().strftime("%Y-%m-%d@%H:%M:%S")		
	print(curSensorID + " Temp = " + str(curTemp) + " at " + datetime.datetime.now().strftime("%Y-%m-%d %H%M%S")) 

aio.send("top-temperature", myTempCase*1.8+32)
aio.send("bottom-temperature", myTempShed*1.8+32)

If you want an infinite loop you can use the following

while True:
    $$ looped code goes here

break can be used to exit the loop
