How do you print the items in a nested list line by line in Python?

Question

For example, if I have:

l = [["apple", "orange", "banana"], ["grape", "strawberry", "raspberry"]]

I'd like if it could print:

["apple", "orange", "banana"]

["grape", "strawberry", "raspberry"]

instead of:

[["apple", "orange", "banana"], ["grape", "strawberry", "raspberry"]]

Easy way to do this?

Use a for loop and iterate through each item in the list:

for item in l:
    print item

You are pretty much tasked to break down that nested array as much as possible.

for i in arr:
    print(i)

But let's say you had a double nested array. You could do:

for i in arr:
    for inArr in i:
        print(i)

If you had a triple nested and wanted to print each, you you do.

for i in arr:
    for inArr in i:
        for subArr in inArr:
            print(subArr)

We use a foreach for each index and then keep using a foreach to look through an even deeper index.

I know you only asked for the first one, but I wanted to give a unique and in depth answer.
