4 channel 16 bit ADC, where is the data stored and how can it be accessed in python

Hi, I installed the 4 channel 16 bit ADC on my raspberry Pi 4B using the instructions on the wiki site and it seems to be working fine, returning number close to 0 when there is no applied voltage and close to 5100 when I apply 1.5V to the A0 channel. this is when I open a terminal and type “cat in_voltage0-voltage1.raw.” My query is where is this data actually stored on the RPi ( I think it is in /sys/bus/iiodevices/iio in the file in_voltage0_raw etc). How can this be accessed via a python script in real time. I’m a complete newbie to the RPi and so I hope someone can help.
