List comprehension vs map

Question

Is there a reason to prefer using map() over list comprehension or vice versa? Is either of them generally more efficient or considered generally more pythonic

Answer 1

If you plan on writing any asynchronous, parallel, or distributed code, you will probably prefer map over a list comprehension -- as most asynchronous, parallel, or distributed packages provide a map function to overload python's map. Then by passing the appropriate map function to the rest of your code, you may not have to modify your original serial code to have it run in parallel (etc).
