Think Python, Free PDF tutorial

Python is a programming language invented by Guido van Rossum. The first version of python was released in 1991.

Python is an interpreted programming language, that is, it does not need to be compiled before executing it. If you have already touched a little programming, you will see that this language has a certain poetry. Programmers often have fun finding the most beautiful / effective way to write a sequence of instructions. Few criticize Python logic - unlike javascript for example .

The goal of this book is to teach you to think like a computer scientist. This way of thinking combines some of the best features of mathematics, engineering, and natural science. Like mathematicians, computer scientists use formal languages to denote ideas (specifically computations). Like engineers, they design things, assembling components into systems and evaluating tradeoffs among alternatives.
