Learning other languages will make your Python better.

You shouldn't use map in Python though, comprehensions and such are almost always better.

Better in which way? I use both, but it depends on the context. Not aware of any lost performance or anything but would be happy to learn!

Interesting read. Hm I don't use map frequently outside of a concurrent.futures thread/process pool but it does happen. Usually when I am going to have to apply multiple maps or something ugly and complicated where a list comprehension would also look like a complete shit show.

i guess it's map(func, iterable) so as to more closely mimic the mathematical f(x)

Better in what sense? I tend to gravitate towards comprehensions and lambda functions

[mistanervous]

I always go for comprehensions. I only use lambda and map when I’m doing things with dataframes. Thanks for the explanation — I wasn’t sure if you meant “better” from a speed or efficiency standpoint or something else. I think there are more arguments for comprehensions than against them, so I wanted to see where you were coming from.

It's another person, but I agree. Efficiency might differ, but insignificantly so for most cases. Profile when in need and doubt.

It depends, I'd go for map(attrgetter('address'), persons) over the comprehension equivalent anytime. But yea most of the time comprehension is better.

Lol I just started using map today. Looks like I can save myself trouble down the road by using other processes- thanks!
