It's hard to say without more details -- what names do you want these
files to have, for instance? Do you want to read the files, or write to
them? The basic idea could be something like:
"""
def openfiles(howmany):
    opened_files = []
    for i in range(howmany):
        opened_files.append(open("prefix%s" % i, "r"))
    return opened_files
"""
This returns a list with file objects.
Why is it necessary to open so many files simultaneously anyway? Perhaps I
misunderstood. :)
