0.简介
本文主要介绍python的注释语法，以及在pycharm中的快捷键。
1.注释
单行注释：以 # 开头，#之后的为注释内容
s = "hello world" #This is comment
print(s) #This is comment
多行注释：用三个单引号 ''' 或者三个双引号 """ 将注释括起来
import this
#You will get the Zen of Python
'''
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!
