循环

while 循环：

count = 0
while True:
    print("count:",count)
    count += 1
if count == 1000:
    break

#break跳出当前循环

 

count = 0
while True:
    if count = 1000:
        break
    print("count:",count)
    count += 1

count = 0
while count<1000:
    print("count:",count)
    count += 1

 

for 循环：

for i in range(10):
    print("loop",i)
else:
    print("end")    #正常循环结束

for i in range(0,10,2):
    print("loop",i)

#0是开始数值，10是结束数值，2是间隔

continue是跳出本次循环

break是跳出当前循环，非全部循环
