I did a similar thing almost 20 years ago, I had to manually verify that the image files from one network drive were the same as the image files from a different location (some internal web-page, I think, I had file access to them, too). That was taking me about one hour each working day, in fact each working night/morning, as this was a night job and I had to do that at the end of the shift (6-7AM).
I had started learning some PHP but very quickly realised (by reading on the web) that Python was way better for this job. With the help with the Python docs page, the Python mailing list (very friendly back then with newbies, maybe still is, haven't been there for a long time), of tkinter (excellent library!) and of py2exe I was able to write a quick script on my Mandrake distro at home, turn that script into an .exe, copy it to a floppy disk and use it at work. Just like that, an ~1 hour job turned into a maximum 2-minute job, the time it took me to open the tkinter-based "program" and press a button or two. One or two years later I was getting my first job as a computer programmer, writing Python, thanks in part to that realisation of "I can make this thing way faster and easier by using Python".
