(1. Please don't top-post.  It gets everything out of sequence, and is 
the wrong convention for this forum
 2. Be sure and do a reply-all, so that the message goes to the forum.  
I'm not here to give private advice.
 3. Use your editor's reply-quoting so that we can tell who wrote which 
parts.  Normally, you'll see that as either a leading ">" character or 
as a "!" character.  And one can tell which parts were written by whom 
by counting the number of those at the beginning of each line)

For my real response, see the end of the message, where it belongs.

Again, what OS are you using?

I have no idea what the pop up comes from, but I suspect you have some 
non-trivial code in that python program, perhaps that creates a gui.  Is 
there any tkinter stuff in it?

As for "Access is Denied", it usually means you tried to access a 
non-existent drive, or one which isn't currently mounted.  For example, 
referencing your CD drive with no platter in it.

I don't know why "print_unicode_table" is undefined, but apparently 
you're missing some code.


And the except clause changed between 2.x and 3.x, so you need to change 
the syntax to match the particular interpreter you're using.  They're 
not compatible, although there's a utility to convert from 2.x to 3.x, I 
don't think there's anything that reverses it.

I'd suggest picking one version, and using only books and references 
that are compatible with it till you're comfortable with the language.
