python ghcomp spaces in names of the outputs

I'm trying to use the ghPython node-in-code. My question is how to extract outputs that have spaces. For example box Corners component has spaces in the names of the output. (in reality I have problems with geco stuff but boxCorners is some common starting point)

so 

| BoxCorners(*args, **kwargs) |
| Extract all 8 corners of a box.
| Input:
| box [Box] - Base box
| Returns:
| corner a [Point] - Corner at {x=min, y=min, z=min}
| corner b [Point] - Corner at {x=max, y=min, z=min}
| corner c [Point] - Corner at {x=max, y=max, z=min}
| corner d [Point] - Corner at {x=min, y=max, z=min}
| corner e [Point] - Corner at {x=min, y=min, z=max}
| corner f [Point] - Corner at {x=max, y=min, z=max}
| corner g [Point] - Corner at {x=max, y=max, z=max}
| corner h [Point] - Corner at {x=min, y=min, z=max}

import ghpythonlib.components as ghcomp

import ghpythonlib.parallel

a = ghcomp.BoxCorners(x).cornera

#a = ghcomp.BoxCorners(x).corner a

#a = ghcomp.BoxCorners(x).corner_a

None of the above works.

Thanks!
