I’ve recently decided to brush up on my programming skills with one of the courses on Udemy. Despite completing a degree in Computer Science back in the day, my recent focus has been away from software development and a lot has changed since I graduated.
At university I studied mathematics and algorithms but actual programming was performed on archaic languages – such as Pascal for high-level and Assembly for low-level programming.
Although they provide a solid foundation, I was looking for something more practical and because of this I ended up taking up Python because of its versatility. Python is not only widely used, but can also be applied to a variety of projects, including data analysis and machine learning.
The course has been very good and Jupyter notebooks with extensive comments and exercises are available for free on GitHub.
You can start applying it in practice straight away or just have some fun with your own pet projects.
If you’re an experienced developer or just want to have some extra practice, I found the below brain teasers quite entertaining:
- Basic coding practice – CodingBat
- Project Euler
- More coding practice – CodeAbbey
- DailyProgrammer – Reddit
- Python Challenge
On the other hand, if you are just starting up and would like some more grounding in computer science, check out Harvard University’s CS50’s Introduction to Computer Science. It’s completely free, online and self-paced. It starts with some basic principles and lets you put them into practice straight away through Scratch, a graphical programming language developed by MIT. You then go on to learn more advanced concepts and apply them using C, Python, JavaScript and more.
The course also has a great community, so I highly recommend checking it out.
