Specify python version and os. I assume python 3 and Windows.

So you've got a filename. You're not using it for anything.
Where's your open? Where's your read or readline?

Are you sure you want a single string nearly the total size of
your 3 files? Could be huge. Might be better to do it
incrementally.
It's a lot safer to include the characters you want, instead of
excluding some of the ones you don't. And many valid words
contain punctuation such as apostrophe.

Need a while loop for that.

That could be another input, or it could be a command line
parameter. Your choice.
