Note:  you can also have comments in multi-lines where the goal is to 
define a sequence or mapping.

 >>> j = [
	1,2, # this is a
	3,4  # list
 >>> j
 [1, 2, 3, 4]

So if you have your heart set on commenting each line of a string, 
spread across multiple lines, you could do something like:

 >>> mylist = ["here we",            # beginning of string
               " are testing",       # middle of string
               " a way to comment",  # etc.
	         " string formations"  # finis

then join it all together at the end (comments automagically gone):
>>> thestring = ''.join(mylist)
>>> thestring
'here we are testing a way to comment string formations'
