I'm not sure I understand you. Do you wish to end up with an array
like this:
#v+
[fileName0][fileLines0]
[fileName1][fileLines1]
...
[fileNameN][fileLinesN]
#v-
In that case try something like:
#v+
>>> files_and_lines = []
>>> for name in file_names:
>>> files_and_lines.append([name, open(name, 'r').readlines()])
>>> print 'Read %d files' % (len(files_and_lines),)
#v-
Add proper error checking.
At least, I think the [].append() method is what you're looking for.
