today is hot day ,  I get a challenge on my work . I need write some Java  interface to call python interface , I haven’t write any python interface . at first , I felt a little hard to do it .a few minutes later ,I change my mind ,I told  myself  you can do it . then  I start to learn the python grammar , 2 hours later , I know how to write python interface .

there are 5 steps to finish the module .

1. upload the file to the server from the client 
2. list the folder and files , back to the page 
3. Java interface send HTTP request call the python interface 
4. python interface analysis the file ,and back the result to the Java interface 
5. the page show the result to customer

when you don’t known how to do you works , don’t be afraid , you need cool down . take some time to thought ,then find a good way to do the work , this way is better than that work without thinking .
