很多python的小技巧，实际调试和工程应用中都可以用到

1、print打印分割符

直接用print中参数sep进行换行，分割线的快速打印。

>>> print('This is a pig','This is a dog','This is a cat')This is a pig This is a dog This is a cat>>> print('This is a pig','This is a dog','This is a cat',sep='\n')This is a pigThis is a dogThis is a cat>>> print('This is a pig','This is a dog','This is a cat',sep='\n-----------\n')This is a pig-----------This is a dog-----------This is a cat

2、zip压缩tuple，逐个元素提取打包

zip命令可以对tuple等可以迭代的元素进行分类打包

>>> name = ['pig','dog','cat']>>> price = ['100','150','200']>>> for name,price in zip(name,price):       data={          'name':name,          'price':price,       }       print(data)  {'name': 'c', 'price': '2'}{'name': 'a', 'price': '0'}{'name': 't', 'price': '0'}
