for循环示例：猜数字游戏
winning_number = 38
for i in range(3):
guess_num = int(input("guess num:") )
if guess_num == winning_number :
print("yes, you got it. ")
break
elif guess_num < winning_number:
print("think smaller...")
else:
print("think bigger!")
else:
print("you have tried too many times..")
while循环示例：死循环
count = 0
while True:
print("I love You!!!---%d" %(count))
count += 1
if count > 999:
break
while循环示例：猜数字游戏
winning_number = 38
count = 0
while count <3:
guess_num = int(input("guess num:") )
if guess_num == winning_number :
print("yes, you got it. ")
break
elif guess_num < winning_number:
print("think smaller...")
else:
print("think bigger!")
count +=1
else:
print("you have tried too many times..")
while循环升级：根据用户输入来决定是否终止游戏
winning_number = 38
count = 0
while count <3:
guess_num = int(input("guess num:") )
if guess_num == winning_number :
print("yes, you got it. ")
break
elif guess_num < winning_number:
print("think smaller...")
else:
print("think bigger!")
count +=1
if count == 3:
countine_confirm = input("do you want to keep guessing..?")
if countine_confirm != 'n':
count =0
