For your health
here is the instruction:
Make the loop print the numbers from 0 to 19 instead of 0 to 9.
print "Counting..." for i in range(10,20): print i
so i print 10 to 19
and the wrong message showed
I t looks like your code does not print 20.
so i changed the code below:
print "Counting..." for i in range(10,21): print i
the message I get :
Make sure you stop at 19!
What should I do?
