I found that after closing files some closed files were left in the
list:
Yes, because you never remove them they will stay there.
If you want to remove them from the list you need you del() them
as part of your close method.
After I call openFiles() and closeFiles() many times, the list will
become fatter and fatter, filled with valueless closed file object. How
could I open the closed file? I can't find the way in python document.
I don't know of a way to open a closed file object, you might want
to store the filename along with the file. Then if you discover it is
closed you can use the name to reopen it.
