Get a thorough understanding of iterators (a crucial part of every Python programmer's toolbox) to solve many real-world problems more efficientlyAbout This VideoExpand your knowledge of Python by delving into iteratorsUse the power of iterators and functional programming to solve real-world problems in PythonApply the techniques learnt in various practical examples throughout the courseIn DetailFunctional programming is a style of programming that is characterized by short functions and little reliance on variables. You will learn what functional programming is, and how you can apply functional programming in Python.In this volume, you will learn everything there is to know about iterators in Python and how crucial they are in functional programming, where they are used, among other things, to implement repetitive logic and coroutines. You will learn about all standard iterators and iterator functions that Python offers. You will also learn to implement your own iterators. Functional programming makes heavy use of iterators, and we will learn how you can use them in functional programming through an interactive calculator application. All videos in the course contains simple, hands-on examples to give you a firm grasp on the subject.At the end of this course, you apply the techniques that you've learned in this course in the real world with a final example (an interactive calculator application) but this time based on a sensible mix of programming techniques, including (but not limited to) functional programming.
