for i in range(0, 22, 2): # range(0, 21, 2) okay too print i
or
for i in range(22): # range(21) okay too if i % 2 == 0: print i
for i in range(1, 20, 2): # range(1, 21, 2) okay too print i
or
for i in range(20): # range(21) okay too if i % 2 != 0: print i
When i % 2 == 0, it's even (divisible by 2), otherwise it's odd.
