总结列表，元组，字典，集合的联系与区别：

1、列表是可变的对象，可进行动态的增加、删除、更新，即str.pop（）和str.extend（）等操作，用[]表示。

2、元组和列表在结构上没有什么区别，唯一的差异在于元组是只读的，不能修改。元组用“()”表示。

3、字典是存储键值对数据的对象，字典的元素都是无序的，且键不能相同，可以通过键，找到值，字典最外面用大括号，每一组用冒号连接起来。

4、集合相当于字典的键，也是一个无序不重复的元素集，用一对{}表示。

I’ve got a hole in my pocket

Loving strangers loving strangers

Loving strangers loving strangers
Loving strangers
It’s just the start of the winter and I’m all alone
but I’ve got my eye right on you
Give me a coin and I'll take you to the moon
Give me a beer and I’ll kiss you so foolishly
Like you do when you lie
when you’re not in my thoughts
Like you do when you lie
and I know it’s my imagination
