to view all videos in a loop so you can set:
for i in range(len(apple)):
print apple[i]
for j in range (len(apple[i])):
print apple[i][j]
While this illustrate double indexing, it can be simplified to
for top in apple:
print(top)
for inner in top:
print(inner)
and give the same output. Indexing is only needed for random access and
for changing a list in place.
