Oh！！！So what！！！continue！！！
第四个程序（基础循环）：
1.
count = 0
while True:
print("count:",count)
count = count +1 #count +=1
if count == 10:
break
2.
for i in range(0,10):
if i <3:
print("loop ",i)
else :
continue
print("hehe...")
3.
for i in range(10):
print('----------',i)
for j in range(10):
print(j)
if j >5:
break
执行结果：
1.
count: 0
count: 1
count: 2
count: 3
count: 4
count: 5
count: 6
count: 7
count: 8
count: 9
