I have a list of file names of a directory, I want to read each one of them.
After reading each one of them, I want to put the results of each file in a
list.
These lists would again be inserted to create a list of lists.
While there's nothing wrong with for loops, Python does provide list
comprehensions which can help simplify list creation.
If you just want a list with each element being a list of the contents
of a file:
all_content = [ open(x, 'r').readlines() for x in list_of_files ]
If you want a list containing a list of filenames and another list
holding the content lists (which you seem to be wanting from your code):
files_and_content = zip(list_of_files, all_content)
Another useful way of storing data such as this is in a dictionary,
using the filenames as keys:
file_content = { x:open(x, 'r').readlines() for x in list_of_files }
What structure is most important is, of course, dependent on what you
want to do with it next.
