1-4 python 注释与换行

一、 单行注释

适用场景：对一行代码，或一段代码进行简要描述

二、 多行注释

适用场景：对一段代码，或一个程序的整体描述

三个单引号：

'''
如下的翻译为：
美丽优于丑陋。
简洁胜于复杂
做也许好过不做，但不假思索就动手还不如不做
'''

print('Beautiful is better than ugly.') 
print('Simple is better than complex.')
print('Now is better than never. Although never is often better than *right* now.')
#===========执行结果=================
>>>
Beautiful is better than ugly.
Simple is better than complex.
Now is better than never. Although never is often better than *right* now.
>>>

三个双引号：

"""

"""

三、 换行（方便阅读）

比如说，我们想在now前面进行换行

我们可以在now前面加一个反斜杠，再回车

print('this is very looooooooooog example.\
Now is better than never. Although never is often better than *right* now.Beautiful is better than ugly.')

>>>this is very looooooooooog example.Now is better than never. Although never is often better than *right* now.Beautiful is better than ugly.
