How many stars will the following snippet print to the monitor? i = 4 while i > 0: i -= 2 print('') if i == 2: break else: print('')

The code initializes i to 4. The while loop starts. In the first iteration, i becomes 2, and one star is printed. Then, if i == 2 is true, so break is executed, terminating the loop. The else block of the while loop is not executed because the loop was terminated by break…

Question

How many stars will the following snippet print to the monitor?
i = 4
while i > 0:
i -= 2
print('')
if i == 2:
break
else:
print('')

Explanation

The code initializes i to 4. The while loop starts. In the first iteration, i becomes 2, and one star is printed. Then, if i == 2 is true, so break is executed, terminating the loop. The else block of the while loop is not executed because the loop was terminated by break. Thus, only one star is printed.
