Answer 1

Assuming you only have digits in your input, you can have something like following:

>>> x = '1 2 3 45 87 65 6 8'
>>> num_x = map(int, filter(None, x.split(' ')))
>>> num_x
[1 2 3 45 87 65 6 8]

This will take care of the case when the digits are separated by more than one space character or when there are space characters in front or rear of the input. Something like following:

>>> x = ' 1 2 3  4 '
>>> num_x = map(int, filter(None, x.split(' ')))
>>> num_x
[1, 2, 3, 4]

You can replace input to x.split(' ') to match other delimiter types as well e.g. , or ; etc.
