Since you call the external cksum command, I do not see the value of losing the call to awk ... unless you have this code execute hundreds of times in a loop we did not see.

Code:
while read v1 v2 v3 
do
    echo "$v1$v2"
done < cksum sjreas.py
# or
 declare -a arr=(`sjreas.py`)   # use backticks it is clearer IMO
# you now have an array
echo "${arr[0]}${arr[1]}"
