That is what the line was in your original post, and I explained the
change you needed to do.

I've noticed that you're opening the menu file before the class
statement but reading from it in the __init__ method. It would be better
if you opened the file in the __init__ method itself. You can split a
line on whitespace with:

t = line.split()

It won't then matter how many spaces or tabs are between the fields.
