1. Set up the environment variable
You know I don't have a choice~~
In the beginning was the WINDOWS, and THINKPAD was with Powershell and notepad++,and the Mac pro was so far away from me.
The same was in the beginning with WIN.
All the suffering were made by it; These Error,as I show you below, were the very BIG PIT (大坑) I felt down and felt down, again and again and again:
- NameError: name 'xxx' is not defined
- TabError: inconsistent use of tabs and spaces in indentation
- and "SyntaxError: invalid syntax" is everywhere,
I mean, I can see it thousands of times in one hour!
"Would you please please please please please please please stop talking?”(Hills Like White Elephants, Ernest Hemingway)
And then,I bought a Macbook Pro while doing CH3, but as everybody knows, I need time to get used to Mac OX ,so it's win + mac together, it bring me double troubles when you want to import something or do something else.
I know what you're trying to say... Don't say it...
So,even I hate to ask someone for help, but after hours of fighted with these little Error, I beginning to hate myself and I just want to go to bed!

So why PYTHON?
I am not a programmer.
I don't make a living by coding.
I don't care whether python can help me with my career.
I paid for the OMcourse by myself which I can use these money to buy an APPLE WATCH.
I do have friends as programmer,but everytime we met,we just running or hiking in the mountain.
I have to work 8 or 10 hours one day and it's not that easy,trust me.
I will travel in a foreign country next weekend,but except buying flight ticket I did nothing, I don't know how to go and where to go and I even want to bring the laptap with me so I can coding while waitting in the airport!
That sound crazy, I know. My friend said:"I don't understand why not learning piano or guitar? python? What the hell exactly?"
Maybe I just want to have FUN.you know,as a trail runner and rock music fans, it's natural to do something crazy.
AND,
I am having fun while the program running successfully. I am happy to know I still have curiosity to know the function of every code.
Maybe someday I can do something for my friend,or do someting aobut trail running , rock music or my novel with pyhon,but I really don't care.
I am learning python, I know it's hard,but I won't quit,even I know I will fall down again and again (we should import 'for' here,right?)
OK,so that's the point.
That's the whole point.
