今天是30天程序语言研究的第七天，研究的语言一样是python,今天主要学习的是while和猜数字游戏

笔记：

while回圈 -重复执行直到判断为false为止

i=1
while i<=５:
print(i)
i += 1 # i=i+1
print("回圈结束") #print 1 2 3 4 5 回圈结束

猜数字游戏

secret_num = 77
guess = None #预设为none
#没限猜的次数
while secret_num != guess:
guess = int(input("请输入数字: "))
if guess > secret_num:
print("小一点")
elif guess < secret_num:
print("大一点")
print("恭喜赢了")
#限定猜的次数
secret_num = 77
guess = None
guess_count =0
guess_limit = 3
out_of_limit = False
while secret_num != guess and not(out_of_limit):
guess_count += 1
if guess_count <= guess_limit:
guess = int(input("请输入数字: "))
if guess > secret_num:
print("小一点")
elif guess < secret_num:
print("大一点")
else:
out_of_limit = True
if out_of_limit:
print("抱歉你输了")
else:
print("恭喜你赢了")
