Using a hex string as an address variable

Question

I'm trying to create a few I2C objects for my raspberry pi and want to cycle through addresses 0x48..0x4B. However I can't figure out how to send the hex address value to the method properly. To simplify things, here is the code just trying to send the first value:

import board
import busio
import adafruit_ads1x15.ads1115 as ADS

i2c = busio.I2C(board.SCL, board.SDA)
address_as_int = 72
address_as_hex = hex(address_as_int)
print (address_as_hex) # returns 0x48 like it's suppose to
try:
    ads0 = ADS.ADS1115(i2c, address = address_as_hex) # Errors out
except:
    print(f"Didn't find a device on {address_as_hex}") # Didn't find a device on 0x48

But running this:

ads0 = ADS.ADS1115(i2c, address = 0x48)

finds my device.

My guess is that the method is seeing address_as_hex as a string and not a hex number, but even if I declare the string a hex number like this

ads0 = ADS.ADS1115(i2c, address = hex(address_as_hex))

It still doesn't see it as a proper hex address.
