用while语句输出1 2 3 4 5 6 8 9 10

import time

count=1
while count<=10:
    print(count,time.time())
    if count != 6:
        count=count+1
    else:
        count=count+2


print('the end')

采用while....continue语句

count=1
while count<10:
    if count==7:
        count=count+1
        continue
    print(count)
    count = count + 1

else:
    print('else')

输出为：

1
2
3
4
5
6
8
9

 

continue终止当前循环，进行下一次循环，break终止所有循环

 

count=0
while count<3:
    user=input('please input ID>>>>>:')
    pwd=input('please input your psaaword')
    if user == '''hello''' and pwd == '''world''':
        print('welcome to the unit')
        break
    else:
        print('try it again')
        continue

输出为：

please input ID>>>>>:90
please input your psaaword90
try it again
please input ID>>>>>:90
please input your psaaword90
try it again
please input ID>>>>>:hello
please input your psaawordworld
