Question

in my python code i want to create a list of lists…in a loop …
but after completion of the loop i end up with the same list in all elements…is it because the lists are pointed to and not stored ? If so, how can i come up with a solution to my problem ?
Following is my code

    list_lists=list()
    list_temp=list()
    for i in xrange(n):
        ind_count =0
        del list_temp[0:len(list_temp)]
        for j in xrange(no_words):
            if inp[i] == words[j]:
                list_temp.append(j)
        list_lists.append(list_temp)

Instead of deleting the items of your list (del list_temp[0:len(list_temp)]) just assign a new list: list_temp = list(). You can also use the shorthand: list_temp = []

The problem that you are facing is that you are always reusing the same list you created in the second line: list_temp = list(). You are just inserting references to this one list over and over again.
