If you need 50 open files, you almost certainly want to have a way of
organizing them. Probably they'll be in a list or dictionary. So, if
they're in a list, for example, you can do this:
filelist = []
try:
filelist.append(open(filename[0]))
filelist.append(open(filename[1]))
...
do_something(filelist)
finally:
for f in filelist:
f.close()
