【diary】help others ,help yourself ,coding is happiness

　　Recently ,i learner python in codecademy.I got a lot of help from  Q&A, but sometimes there are no suitable answer for me ,and a lot of people are stucked in some annoying problem.Sometimes ,the system isn't so intelligent so that  can't  recognize the right answer .Sometimes people can't understand the question clearly  .i need to pass the lesson,so i spent lots of time trying different code to solve the problem ,and finally i found out some answer can pass the lesson .

　　At first ,i just continued next lesson ,but i thought ,there must be some people being stucked in such problem .I considering to share my passed answer to others ,but i was afraid of being wrong ,because there are so many people from all over the world ,and there must be some excellent coder .After thinking over ,i posted some reference answer ,because i thought ,no one knows me ,there is no need to be afraid .If i am wrong ,i can get some help from others .If i am right ,i can help others .There is a good way to improve all of us ,that' just a happy coding world ,isn't it ?
