Hello, am a newbie in python and I have a little project that I did on my own after watching some videos but I ran into issues and might think some experts on here might know the answer.

About the project: I have the folder called Waveform and inside that folder, there are 4 files, and each file containing 4 features such as voltage, currents, speed, max output. I wanted to create a button that will load the folder and then create a button that can scroll through each file and pick a specific feature to export out to a text file. At this moment I am stuck at the very first step which is to load the folder, I will attach the screenshots of my code to see if any experts can notice any errors. Thank you in advance
