After extracting emails...from project 1

After extracting the email from my gmail account using gyb procedure, a directory named ‘bin’ is created and files in directory is shown in the attached screenshot .
question … seeing the size of gyb file in gyb folder seems like the file containing emails but the file is not in txt. format
please let me know if i am on the right track.

Inside these folders, I can see the .eml files are there. Please use python code to read this folder and files in it.
