Thank you very much!
Here it is the final version:

 -----

from time import sleep

sum = 0
sum_stop = 100
while sum < 100:
 num = input("Please enter the number: ")
 sum = sum+num
 if sum < 100:
  print "The sum is", sum
 else:
  print "The sum is > 100 and it is", sum
 print
sleep(10)

Best regards.
