Good books to learn Complex Analysis and Contour Integration? I have completely finished some of calculus, such as Limits, Derivatives, Sequence and series, Indefinite and Definite Integration and many more. And have solved humongous amount questions on these topics. I am also good with basics. So to expand my knowledge more, I wanna self study Complex analysis and Contour Integration as I did for previous topics. Can you please suggest some good books for them? Starting from stratch so that it's easy for me to self study? It don't have to be one book, can be series of books too. Any help would be greatly appreciated, thank you. :)

Starting from scratch and completely rigorous (way more rigorous than a few suggestions on this page, no hand-waving whatsoever) is "Theory of Functions of a Complex Variable" by Markushevich. If you have the freedom to invest a good time in it, it is the book to go.
