I have to confirm that the nested loops have been implemented correctly

Furthermore, the questions says, "After filling the blanks in the code, run this check to see if your implementation works correctly." What do they mean when they say "After filling the blanks in the code?"

Here is the code I have so far:

for x in range(len(companies)):
print(companies[x])
for y in range(len(companies[x])):
    print(str(len(companies[x][y])))

After running the code, the output produces this:

['Warner Bros. Pictures', '20th CenturyFox', 'Universal Pictures']
21
15
18
['Whole foods', 'Starbucks', 'Walmart']
11
9
7

However, the intended output is supposed to be:

['Google', 'Facebook', 'Apple']
6
8
5
['Warner Bros. Pictures', '20th CenturyFox', 'Universal Pictures']
21
15
18
['Whole foods', 'Starbucks', 'Walmart']
11
9
7

How do I rewrite my code to match the correct output?
