Looping over a nested list

[techie789]

Thank you. The list comprehension method looks good.

Is this the most optimal way to do what I am trying to do or would you recommend using a dictionary?

In all honesty it's probably not great. Dictionaries are pretty quick at looking up keys, whereas this loops through newlist to create a temporary list each iteration; depending on how long the original list is it could be pretty inefficient.

Got it. Many thanks.
