Extracting data from files

You are a data scientist for a climate research organization. To update some models, you need to extract temperature data for 3 regions you are monitoring. Unfortunately the temperature reading devices are quite old and can only be configured to dump data each day into a folder called temps on your server. Each file contains the daily temperature for each region.

Your task is to extract the data from each file (by concatenating) into the relevant variable and print it out. The temperature in the file region_A needs to be assigned to the variable temp_a and so on.

You will later do some more advanced calculations on these variables.
