Well, I assume that I have to repost the issue rather than to reply under the old one. Here's the explanation.
R:
testing(7, 8)
testing(13, 16)
testing(17, 22)
Python:
testing(easyline(7), 3432)
testing(easyline(13), 10400600)
testing(easyline(17), 2333606220)
testing(easyline(19), 35345263800)

Well, here's the explanation.
R:
testing(7, 8)
testing(13, 16)
testing(17, 22)
Python:
testing(easyline(7), 3432)
testing(easyline(13), 10400600)
testing(easyline(17), 2333606220)
testing(easyline(19), 35345263800)

I beleive the testing codes with R are incorrect though there are 181 people on the done-list with R. Plz check this.
