Do not do system update before g

Do not do system update before go to sleep

today's plan is to follow 《head first python》to do some simple programming with python on my own PC, but met problem one first step which is i cannot find IDLE on my PC, so insdead of finding another editor I made a silly decision which is update my Mac system...

So when I got the updating remaining time I think I need to change plan today

And thank got I did some simple try on my company's PC which gave me some first understanding about python and i made myself a heart

Do not do system update before go to sleep

just like all othe programming language it can be romantic and fun

after that I found the turtle model which allows you to draw something on a canvas very similar with CSS fun and simple but not sure if it is useful or not

No idea if I can be still awake after the installation finished as today I caucht cold and need to go to bed early

if the updation is faster than I think I really want to at least find an editor to make sure I can do something directly tomorrow and also give another try with mysql installation

But seems I really need to go to bed

So that is all for day2

OK, I got up from bed and checked my PC after update complete

And found homebrew doesn't work and get a 

Error: Failure while executing; `git config --local --replace-all homebrew.private true` exited with 1.

This seems sucks and I googled there is a cmd can check what is wrong with your homebrew

brew doctor 

Tried it but simply got some warning and still cannot solve the problem

After further investigation I finally found the root cause is Mac will automatically uninstall xcode after each update

so you need to install it back by

xcode-select --install

And the installation takes a long time, and today's LL is definitely: Do NOT do system update before go to bed...

By the way, during the installation of xcode I searched python 3 on my PC and find some .py file when I trying to open them I finally find the IDLE3

So I did my first try and found the syntax is really strict especially with space

After corrected everything and ran successfully with my first manually inputed python, and successfully fixed the homebrew problem

I finally can go to bed
