Tkinter FileDialog
If all of the files you need to open are accessible from a central location you could have your if statement open the file they needed for them.
Try setting those files as variables:
t_test = r'Path\To\File\location\t-test.file'
and so on for the rest of your files.
Then, instead of telling them what to open just open it with os.system():
os.system(t_test)
Don't forget to import os with the rest of your imports.
I figured it out on my own, with some help from the internet of course. My updated code is:
