How to print only last line in a while loop

count = 0

while count ** 2 < snum_:
    print "Using search with increment 1, the root lies between", count,"and", count + 1
    count = count + 1

How do I get the loop to only print the last possible line?

You could save the string you want to print and print it after the loop:

count = 0
result = ''

while count ** 2 < snum_:
    result = "Using search with increment 1, the root lies between %d and %d" % count, count + 1
    count = count + 1

print result

You can try this: 

count = 0

while count < 4:
    print('hi')
    count += 1
else:
    # Replace below string with what you wish.
    print('end')

+= means count + 1. else is reached after while finishes (will not print, if you break the loop instead of letting it finish normally).

With a for-loop and itertools.count():

import itertools
for count in itertools.count(1):
    if count**2 >= snum_:
        print "Using search with increment 1, the root lies between %d and %d" % count-1, count
        break

But the general idea can also be applied to your while loop: When count**2 is no longer less than snum_, print and break.
