...metus at tortor pulvinar varius.\n'
>>> f = open('Desktop/lorumipsum.txt')
>>> f.readlines()
['Lorem ipsum dolor...

Learn how to code with python: Lesson 1 - Hello World!

In this first lesson of my free video course: Learn how to code with Python, you will write your first python program. You may think that the program isn't much, but actually it is a big step to get code to run for the first time in a new programming language. It is also kind of a tradition that whenever you are introduced to a new language you start with printing a message to the screen, that says: "Hello World!".

Learn how to code with python video course

Below is an intro to my free mini video course:

Learn how to code with PythonIn this course I will teach you basic coding skills using the Python programming language. I believe that anyone should learn how to code. Coding / Computation is all around us and you will understand more of the worldaround you if you know how to code. It is not my intention to make everyone a software developer,  but coding is a skill like reading and writing. And it can be a lot of fun as well.
