Worth noting that map() can be parallelized whereas a list comprehension can't necessarily (since it is an explicit loop). The multiprocessing module allows trivial map parallelization, but can't work on list comprehensions.

It's more than just stylistic.

So I have coded everything from dumb web servers (tm), to high performance trading engines (tm). I have toyed with doing the list in parallel thing... and used it in a toy GUI tool or two I wrote... but never really found it that useful in the real world. If you actually want high performance, doing a parallel map is not going to be fast enough. If you are a dumb web server, it's a waste of overhead 99% of the time.

But hey, if you want to use map when you actually need to do a parallel map, cool. But seems very very uncommon. ~ 1 in 10,000 maps I write.

I don't think this is the case, list comprehensions can be expressed as syntax sugar over list functions, it's how they work in Scala for example

map() can only be parallelized if the function has no side effects. If there are no side effects, list comprehensions can be parallelized just as well
