In [1]: import numpy as np
In [2]: nums = np.array([12, 37, 5, 42, 8, 3])
In [3]: even, odd = nums[nums % 2 == 0], nums[nums % 2 == 1]
In [4]: print(even, odd)
[12 42 8] [37 5 3]
However I have tried a different apporach but strangely it didn't work. Eight is missing from the even list. And I don't know why. Here I pop() a number and put it to the even list if some condition. So the original list sould contain only odd numbers at the end. Doesn't work
In [1]: numbers = [12, 37, 5, 42, 8, 3]
In [2]: even = [numbers.pop(numbers.index(n)) for n in numbers if n % 2 == 0]
In [3]: even
Out[3]: [12, 42]
