If you have used keyword arguments in your functions, you have already used dictionaries! Just think about it - the key-value pair is specified by you in the parameter list of the function definition and when you access variables within your function, it is just a key access of a dictionar...

Create pipelines using Functional Data Structures, Higher Order Functions and functions. Pipelines are a chain of functions that always return a value. Pipelines can process both pure and impure values. Use fold to let a pipeline return a pure value. With a few lines of code we can express ...
There are also functions attached to lists calledmethods. To display all methods available, call thedir()function and give it a list as an argument. >>> dir(my_list) # listing all methods Note that equality operator (==)creates a reference to the same list, and not a copy of it. ...

Let’s remind ourselves of the four built-in data structures available to us. We’ll take each data structure in turn, working through list, dictionary, set, and finally tuple. Working at the shell, let’s create an empty data structure using the data structure built-in functions (BIFs fo...
