I think you have lost # at the beginning of the file

I guess, you'd also need to add "b" in line 17
inputData = pickle.load(open(inputFile,'rb'))

I got error below when I run your script. Please check it to me?
AssertionError: Usage: pickleViewer <input.pkl>

ZanKa24, Remove the line

assert len(sys.argv) == 2, "Usage: pickleViewer <input.pkl>"

if you running it from the IDLE directly.

I developed this https://pickleviewer.com/ for this reason :)

I honestly just dumped this here for myself but it's now updated to fix bugs and work in Py3
