Believe me. There are no videos on youtube other than you to my knowledge that explain the design pattern before and after effect with real practice examples . Thank you so much !
-
Thank you for not making 'hello world' tutorials!!!!!!! Keep going! :)
-
Honestly, this is some of, if not the best, intermediate/advanced level content out there! Too many people focussing on the pure basics, but you presented this in such an easy to understand way! Forget binging Netflix, time to binge Arjan 😂 Thanks a lot ❤️
-
This is exactly the sort of level of information I need at my stage of learning to code. thank you so much really appreciate the thought you've put into this!
-
Highly Underrated Video, should have more than a million views. There are very important concepts which programmers don't even know. Thanks for the High Quality Content !!
-
I absolutely love this channel. I have always really struggled with the idea of trying to identify what "intermediate" level coding is, and I would say this channel really fills that gap in the existing YouTube literature for python coding. I think this channel is going to really level up my skills, can't wait to see more!
-
It is not even possible to get this kind information from paid sources, but you are great person that making these kind of valuable lessons available on youtube. Thank you very much for all the effort, Respect.

Great video. I'm a data scientist but moving more and more to software development. I'm still having a hard time writing good code, but I'm starting to be able to recognize it when I see it. Videos like this are super helpful with that.
-
Fantastic series! I think all of the concepts you're discussing are vastly under-appreciated
-
I noticed cohesion and coupling are pretty similar to the concept of between and within dispersion in cluster analysis. Kinda cluster should be maximized by between-cluster distance and minimize by within distance of elements inside. Why I noticed this only after your video? Your explanations are really genious.
-
Love your work man. Your calm and clear delivery is a breath of fresh air. Keep it up.
-
This series is great, both the topics and your way of explaining stuff. Thanks for taking the time to make these!
-
Your videos are absolutely amazing! I can only imagine how much work and hours you have put into this. Thank you for sharing your knowledge to all of us learning Python!
-
Absolutely outstanding video Arjan! I've been coding Python for ~5 years and always saw these techniques in play but never really knew where they were coming from. Looking forward to the rest of the series.
-
Your videos have changed the way I code. This is my second time going through this playlist. Since watching your videos I have been writing better code. Trying to do better every time. I have even done better at interviews. Thank you so much for great content. Merry Christmas and Happy New Year!
-
This is a such a great series! I've been looking for intermediate level design content for years. You've nailed the delivery and content. Looking forward to seeing more videos.
-
Holy cow, this is first video that I am subscribing, liking and sharing right away. This is a gem. Thank you very much Arjan.
-
I was so frustrated of going through tonnes of leetcode interview exercises/tutorials and was looking for a more philosophical understanding of how to design python codes. Then I found your channel, I am now more confident after going through some if not all of your videos. Keep it up! The coding challenge is soon, will update if your content helped me land the job.
-
Great stuff, thank you!! I really appreciate this kind of intermediate+ material. There is very little available. Looking forward to the rest of the series.
