[Tutor] new user question about while loops

[Pujo Aji]

Hello,
 I'm not so sure about your problem, but
probably this code can help....

sumHead, sumTail = 0,0

listHeadTime = []
listTailTime = []

for i in range(100):
time_start = time.clock()
coin = random.randint(0,1) # 0 head, 1 tail
time_stop = time.clock()
time_duration = time_stop - time_start

if coin == 0:
sumHead += 1
listHeadTime.append(time_duration)
else:
sumTail += 1
listTailTime.append(time_duration)

print sumHead, sumTail
print listHeadTime
print listTailTime

 Cheers,
pujo
