7.while循环，exit，contiune，break，死循环

while循环
count=0
while count<100:
    print("我要一个小宝宝")
    count+=1

求偶数
count=0
while count<100:
    if count%2==0:
        print("我要一个小宝宝", count)
    count+=1

求奇数
count=0
while count<100:
    if count%2==1:
        print("我要一个小宝宝", count)
    count+=1



import  random
n=random.randint(1,10)
print(n)
count=0
while count<5:
    user_guess=int(input("请输入："))
    if user_guess>n:
        print("太大了")
    elif user_guess<n:
        print("太小了")
    else:
        print("niubility")
        exit() # 终止整个程序，print（count）不打印
    count+=1
print(count)

import  random
n=random.randint(1,10)
print(n)
count=0
while count<5:
    user_guess=int(input("请输入："))
    if user_guess>n:
        print("太大了")
    elif user_guess<n:
        print("太小了")
    else:
        print("niubility")
        break # 终止整个循环，print（count）打印
    count+=1
print(count)

count=0
while count<100:
    count+=1
    if count>10 and count<20:
        continue # 终止当次循环，继续下次循环
    print(count)

else:# 当循环正常结束，条件不成立了，执行
    print("Dsds")

break continue 等需要在循环语句中才能使用。for循环也可以


死循环
deadloop 
while true:
　　print("你是傻逼吗？")
