There are many ways to accomplish this.  Here's one way.  Assuming you
have the following line numbers (turn on line numbering with :set nu)

10 a=['a','b','c']
11 for i in a:
12     do_something(i)
13     print i

Now type
:10,13s/^/#/g

That should do it.  Basically, you're looking for the beginning of each
line (^) from 10 to 13.  Then you're inserting a # in each spot.
