If your definition of `elegant' includes `short', here is a one-liner to
do this. It maps a list [0,1,2,...] to a list of open files:
[<open file 'file00', mode 'w' at 100bb2e8>,
<open file 'file01', mode 'w' at 100bb338>,
<open file 'file02', mode 'w' at 100bb388>,
...]
files = map(lambda i: open("file%02d"%i, 'w'), range(N))
Then, files[i] gives the i'th file.
