Last character when parsing from sys.stdin not printing properly

I'm learning Python and for some reason I have a strange problem with negative indexes. Instead of getting the last character I get an empty string. And instead of getting all character but last I get the whole string back. Here is the code I'm using:

print('Starting loop')
for line in sys.stdin:
   last = line[-1]
   print 'last = ' + last 
   allButLast = line[:-1]
   print 'AllButLast = ' + allButLast

The result:

Starting loop
123
123
last =  

AllButLast = 123
last = 

AllButLast = 123

Add line = line.rstrip() at the beginning of the for loop to get desired value. Currently newline is being captured as line[-1], so you need to remove that first. The enter that you press just after typing 123 is nothing but a newline.
