In this lesson I bring together the few basics discussed in the previous videos and this video. To do this I will discuss one more important principle in programming and that is:

Datatypes

I have already introduced some datatypes like strings, integers and floats. But there are more types you need to know about before we can continue.

One of the most useful things to know how to do when just learning how to program, is knowing how to read and write text files. In this video I show you how to do just that.

Example code from the video:

...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!

Image
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!".

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.
