break 跳出循环 （做到这歌结果就结束）

continue 结束本次循环 （只是这个结果不要，继续做）

跳出循环
while condition（条件） expression(表达)
条件满足的情况 跳出循环

break

编写文件

x = 0 
while x <= 10:print(x, end=" ")x += 1
print("小于等于10")y = 0
print("加多一个条件，当y等于6的时候跳出循环        break;   这个是; 号 不是:")
while y <= 10:if y == 6:break;print(y, end=" ")y += 1

输出结果

0 1 2 3 4 5 6 7 8 9 10 小于等于10
加多一个条件，当y等于6的时候跳出循环      break;   这个是; 号 不是:
0 1 2 3 4 5

编写文件

print(1)
dalao = ["aa","AA","bb","BB"]
for xiaodi in dalao:print(xiaodi)# .startwith() 以什么开头的方法 
# 列表 dalao 
print(2)
# 如果不是a 开头的 就 跳出循环
dalao = ["aa","AA","bb","BB"]
for xiaodi2 in dalao:if not xiaodi2.startswith("a"):break;print(xiaodi2)
print(3)
#如果是  a 或者 A  开头就打印 
dalao = ["aa","AA","bb","BB"]
for xiaodi2 in dalao:if xiaodi2.startswith("a") or xiaodi2.startswith("A"):print(xiaodi2)

编写

dalao = ["aa","AA","bb","BB"]
dajie = [1,2,3,4]
i = 0
while i < len(dajie):print(i)i += 1

输出

0
1

3

编写

dalao = ["aa","AA","bb","BB"]
dajie = [1,2,3,4]
a = 1
while a < len(dajie):for d in dalao:print(d,end=" ")print(a)a += 1

输出

aa AA bb BB 1
aa AA bb BB 2
aa AA bb BB 3

编写

break 满足当前条件 就跳出循环

dalao = ["aa","AA","bb","BB"]
dajie = [1,2,3,4]
a = 1
while a < len(dajie):for d in dalao:if d.startswith("b"):break;print(d,end=" ")print(a)a += 1

输出

aa AA 1
aa AA 2
aa AA 3

编写

continue 满足当前条件的 本次忽略 然后继续

dalao = ["aa","AA","bb","BB"]
dajie = [1,2,3,4]
a = 1
while a < len(dajie):for d in dalao:if d.startswith("b"):continue;print(d,end=" ")print(a)a += 1

输出

aa AA BB 1
aa AA BB 2
aa AA BB 3
