Rounding a list of floats into integers in Python

Question

I have a list of numbers which I need to round into integers before I continue using the list. Example source list:

[25.0, 193.0, 281.75, 87.5, 80.5, 449.75, 306.25, 281.75, 87.5, 675.5,986.125, 306.25, 281.75]

What would I do to save this list with all of the numbers rounded to an integer?

Answer 1

You could use the built-in function round() with a list comprehension:

newlist = [round(x) for x in list]

You could also use the built-in function map():

newlist = list(map(round, list))

I wouldn't recommend list as a name, though, because you are shadowing the built-in type.
