Type Variables and Operators

Chapter 10. Collections

In the last chapter, we learned about functions and scope of variable. In functions, we learned about defining a function, functions with arguments, functions with arguments and return type, functions with default arguments, functions with variable length arguments, and, finally, in functions, we saw how to use key-value pairs as variable length arguments. We covered the topic of scope variable and memory management. In this chapter, we will touch the essence of every programming language, that is, collections. Some of the topics under collections such as list, dictionary, and tuple have already been covered in the previous chapter. In this chapter, we will be looking at counter, deque, ordered dictionary, default dictionary, and named tuple.
