TypeError: 'list' object is not callable while trying to access a list

I am trying to run this code where I have a list of lists. I need to add to inner lists, but I get the error

TypeError: 'list' object is not callable.

Can anyone tell me what am I doing wrong here.

def createlists():
    global maxchar
    global minchar
    global worddict
    global wordlists

    for i in range(minchar, maxchar + 1):
        wordlists.insert(i, list())
    #add data to list now
    for words in worddict.keys():
        print words
        print  wordlists(len(words)) # <--- Error here.
        (wordlists(len(words))).append(words)  # <-- Error here too
        print "adding word " + words + " at " + str(wordlists(len(words)))
    print wordlists(5)

Solution 1:

For accessing the elements of a list you need to use the square brackets ([]) and not the parenthesis (()).

Instead of:

print  wordlists(len(words))

you need to use:

print worldlists[len(words)]

And instead of:

(wordlists(len(words))).append(words)

you need to use:

worldlists[len(words)].append(words)

Solution 2:

To get elements of a list you have to use list[i] instead of list(i).

Solution 3:

wordlists is not a function, it is a list. You need the bracket subscript

print  wordlists[len(words)]

Solution 4:

I also got the error when I called a function that had the same name as another variable that was classified as a list.

Once I sorted out the naming the error was resolved.
