Reflection of class on Oct 27th
  In latest class before I went to galley for lunch, I installed the Chinese input method in my Raspberry Pi 3 but it could only work after restarting. So the first thing I paid attention to today after I plugged in the charging and started the computer was the upper right corner of the surface where the input method icon located. Luckily, it works very well today, I can switch the Chinese input method by pressing ‘command + blank’ instantly so that I can type Chinese characters conveniently in Chinese search engine if I wanted to search some relative information of Raspberry Pi.
  Well, today I read chapter 3 and did some practice about creating interactive programs which emphasized the interaction between users and programs. As we all know, communication and interaction between users and programs are pretty important because most programs need users’ feedback when they provide dedicated service for users like online shopping and hotel booking.
  We usually need sigh up in an interactive program or input some necessary information to use it better, so input statement is integral to achieve this function. When I used Python 3 to type some input statement and tried to function it by pressing F5, there was an error feedback displayed on the screen that mentioned me what I had inputted was not valuable. I had to type in double quotation mark before I inputted the answer to the right place to avoid the appearance of the same error.
  I was very confused about it because I followed the steps of example showed in book and could not find any particular notes about it. So why there was an error with right operation? Suddenly I realized that the text editor what I used was not the newest version provided by Raspberry Pi. So I opened the newest version and type in same statements on screen and press F5 to examine it. Fortunately, it worked well, a successful troubleshooting.

  Except input statement, I learned a lot about how to add notes in my codes regularly and join strings together to assemble an entire sentence. Of course, they were not difficult for me. I tried to create my own interactive program by using Python 3 after I did enough practice in class, but the class was almost over. Well, I would do it in next class after I finished regular learning because it was necessary for me to understand interactive program deeply.
