I have four different lists. headers, descriptions, short_descriptions and misc. I want to combine these into all the possible ways to print out:

header\n
description\n
short_description\n
misc

like if i had (i'm skipping short_description and misc in this example for obvious reasons)

headers = ['Hello there', 'Hi there!']
description = ['I like pie', 'Ho ho ho']
...

I want it to print out like:

Hello there
I like pie
...

Hello there
Ho ho ho
...

Hi there!
I like pie
...

Hi there!
Ho ho ho
...

What would you say is the best/cleanest/most efficent way to do this? Is for-nesting the only way to go?
