After playing with this, it seems the key is to pass objects to the ANSI
terminal via the following:
import ANSI
crt = ANSI.ANSI(25,80)
head_output = ["line 1 ABCDEFGHIJKL", "line 2 ABCDEFGHIJKL",
"line 3 ABCDEFGHIJKL", "line 4 ABCDEFGHIJKL",
"line 5 ABCDEFGHIJKL", "line 6 ABCDEFGHIJKL"]
for i in head_output:
crt.write(i + "\n")
print crt.get_region(2, 6, 5, 10)
Output from ANSI terminal region:
['2 ABC', '3 ABC', '4 ABC', '5 ABC']
