Yes you can. That is an advantage of comtypes. 

Since I don't know what "circle" variable contains I would suggest you also to 
try.

hatch.AddOterLoop(array.array('u',circle[0])), where I guess that 'u' defines 
an object data type. You can also try, 

hatch.AddOterLoop(circle[0])

I have never used AutoCad so I am just guessing. Pleas show what variable 
"circle" contains.
