Let me add this information to clarify the context in which I got this error 48. It doesn't make sense to me, and it might not to you.
This morning, I opened my webapp (vsearch4web.py in the terminal code above) and noticed a whole bunch of code I had not typed. I also noticed something weird about the file path in the title bar (it seemed to be in my downloads folder). So I created a completely fresh file, retyped everything, and replaced the older one in the folder with this one. THEN, I ran the program at my terminal, and got this error 48 in response. Does any of this make sense? Thanks, Tamara -- https://mail.python.org/mailman/listinfo/python-list
