Why reference this? Unless you added zero-width joiners in the move, 
this is irrelevant noise.

Upgrade to 3.1 as soon as you can. Works better.

I otherwise concur with R. James as there is no syntax error posted.
To make sure there is nothing invisible in that line, do
print(repr("for k in range(I):")) # should be no escaped chars and
print(len("for k in range(I):")) # should be 18, I believe
