Question

I’d be interested in some before-and-after c# examples, some non-idiomatic vs idiomatic examples. Non-c# examples would be fine as well if they get the idea across. Thanks.

Answer 1

Idiomatic means following the conventions of the language. You want to find the easiest and most common ways of accomplishing a task rather than porting your knowledge from a different language.

non-idiomatic python using a loop with append:

mylist = [1, 2, 3, 4] newlist = [] for i in mylist:     newlist.append(i * 2) 

idiomatic python using a list comprehension:

mylist = [1, 2, 3, 4] newlist = [(i * 2) for i in mylist]
