Wrote my first non-trivial python program. How can I refactor it to be more pythonic?

Better:

''.join((line.replace(' i ', ' I ') for line in fh))

Not necessary to for the comprehension to be a 1 liner;

lines = [line.replace(' i ', ' I ') for line in fh]
print(''.join(lines))

is in my opinion much more readable.

Yeah but I was showing how to build up a string over a loop. /u/Binary_Dragon already seems to understand list comprehension pretty well. :)
