> floats = [1.5, 1.9, 2.0, 1.0] > unique_integers = len(set(int(f) for f in floats))
And it can be written with set comprehension too.
>>> floats = [1.5, 1.9, 2.0, 1.0]
>>> len({int(x) for x in floats})
2
As my personal recommendation, map is OK only
when first argument is predefined.
In other words, I strongly prefer comprehension to map+lambda.
