I totally agree with everything Steven said.
However there is one glaring mistake in your code....

What do you think that last row is doing?
Whatever it is, you are almost certainly wrong.
But eventually it is likely to throw an index error...

It works perfectly. It prints out i and i+2 for every member of 
firstrow. Whether that's what you want to do is another matter.

As Steven said, try working out what you want to do first,
then write the code.
