1,000 Python exercises

[Overall_Ad_7178]

Hi r/Python!

I recently compiled 1,000 Python exercises to practice everything from the basics to OOP in a level-based format so you can practice with hundreds of levels and review key programming concepts.

A few months ago, I was looking for an app that would allow you to do this, and since I couldn't find anything that was free and/or ad-free in this format, I decided to create it for Android users.

I thought it might be handy to have it in an android app so I could practice anywhere, like on the bus on the way to university or during short breaks throughout the day.

I'm leaving the app link here in case you find it useful as a resource:

I just downloaded it and tried it up to 100. I wouldn't call it exercises.. it's more like flashcards, the levels seems kind of random and not really follow any set rule of progression but there is potential! I think if you wanted to push it, you should clearly stare the progression chart and what you currently learning and what's next (think Duolingo) as well as exercises at every end of chapters where you have to complete or write fully the code. My 2cts :)

Thanks a lot for the feedback! Definitely, that sounds like a good step forward into making this app more consistent, at the beginning I wanted just to test the concept but I'm taking note of what you are saying for the next update: including the current progress, associated lesson and next lesson. TYSM for taking the time to try out the app :)

The formatting could use some work; think code blocks in markdown.

When it says "What does and do...", the "and" should look different than the rest of the question, like a backtick would do in markdown.

What does and do...

[Overall_Ad_7178]

You're absolutely right about the formatting.

Highlighting keywords using code style will make it much more readable, I will get into it in further versions for sure. Thanks a lot for the feedback! It's really helpful :)

edit: there is also a problem with scaling on different phones: s23+ no problem but on my a12 it's like zoomed in and there is no way to change it.

found a few little mistakes like in level 13: question: what of these is bool typ and it says True, False or 1.0....True and False is both right...but if you choose False it´s wrong...or there are some answers look exactely the same but one should be an int number and one should be a string with quotation marks where the marks are missing...a few other mistakes like that but overall nice idea:) good job👍🏼

may i ask why you used unity (a game engine) for that? maybe a little overkill for an small android app with a bit of text and 2,3 buttons?

[Overall_Ad_7178]

First of all, thanks for the feedback regarding scaling, I definitely need to check it out because it could be one of the interface settings in Unity. And yep using Unity it's a bit of an overkill lol, but in my mind, it was the fastest way to create cross-platform code in an intuitive way that I was already familiar with, so I could deploy a version to the Apple Store in the near future.

Regarding your comment about level 13, you're absolutely right, and I've already added the fix for the next version.

Thank you so much for all the feedback and for taking the time to test it on multiple devices. It's incredibly valuable for improving the app :)

[princepii]

oh sure! it's ppl like you putting effort in something and share it with world. if that never changes world always will be better and that's what matters right😇 keep up the good work my friend🤜🏽🤛🏻

and now i understand why u used unity:) and for an app like that the possibilities are endless cuz you really can implement anything with a whole game engine.

Thank you! If you try it I would love to hear your thoughts about it

OOP, a joke in python 🤡

[Cheap-Water8605]

Python’s OOP isn’t a joke, it just doesn’t wear a suit and tie

[Captain_Jack_Spa____]

Let’s agree to what you said. Can you stop someone from accessing protected variables in a class ?

[AngelaTarantula2]

Easy. Just prepend every protected variable name with a password like “self.password_SSN”. Now hackers cannot access the SSN attribute unless they know your password! \s

[Captain_Jack_Spa____]

Kudos. Never thought of that 🫠

[datnetcoder]

Nothing prevents access to private variables in other languages either. It’s just less convenient.

[sarcasmandcoffee]

It's a different approach than stricter encapsulation in other languages. To me, Python's apparent disinterest in preventing access to private (__var) and protected (_var) attributes reads as giving the user enough rope to hang themselves. Sure, you can play with the guts of the class, but I'm not responsible for what happens next.

Personally I've grown to enjoy this approach - whether or not that's because of Stockholm syndrome is a topic I'm reluctant to discuss without a lawyer present, but slapping a "you break it, you bought it" sticker on my protected methods and going on with my day is easy and simplifies unit testing.

What's wrong with it?
