To be honest I expected you would have used an automated testing software to make your tests interact directly with your application gui. Probably since this is a general video about testing is better like this, I don't know of you or your followers are interested and if they knows about this kind of software, by the way I'm using for my kivy/kivymd application this combination to have pretty good automated tests: - telenium : application that is able to interact with kivy gui using xpath to select widgets - pytest : a test suite for python - pytest-bdd : which is a plugin for pytest that implements bdd and permits you to use gherkin language to define your tests step and bind python methods to your gherkin steps. I hope this information could be useful.

[@PythonSimplified]

Thanks for the AWESOME Kivy testing tips! 😃 Much appreciated! Telenium is definitley on my list, I will cover it in a future series of a Kivymd app from head to toe (or tail... should I say 😉). For the current video, I wanted a general testing tutorial that covers what to test and how to test it regardless of the GUI library we're using 😃 Now that it's out of the way - we can move on with more complex/specific stuff. Thanks again! Pinning your comment to the top! Cheers! 🙂🙂🙂

​@@PythonSimplified@Python Simplified I really like the python course you explain it very good and easy. love tour vids

[@rahmanabdullah1049]

You make things so simple to understand and apply. Thank you!

[@bombus1340]

+1 for a video about SQL Injection! I've seen videos about what to do to avoid them, but nobody demonstrates examples for Injections and it always feels like "avoid it, because I say so". I'd like to see exaples for possible Injections attacks to get the full picture.

[@PythonSimplified]

Great! I've seen so many requests already, it's safe to assume a simplified tutorial is needed! 😉 We'll do the following: I'll design an example webapp that each of us can clone and experiment with on our own device. That way, we are not attacking an actual server, rather than our own local environment. Thank so much for the request! I'll start conceptualizing a very nice tutorial 🙂

[@taskhopper]

Thank you so much for this tutorial honestly. You're such a lifesaver!

[@wagnerjosegertrudesmuitoal3638]

You are absolutely sensational at explaining complex stuff in a straightforward way. Thanks for this video. Now, could you please make some videos about some simple Kivy and Kivymd apps and getting them to run on android?

[@PythonSimplified]

Thank you so much! I already have quite a bunch of simple GUI tutorials for kivy/kivymd! Both for Android and Desktop 😉 Here's the list: 🥝 Mobile App with KivyMD - Python GUI for Android - Binary to Decimal Converter: kzbin.info/www/bejne/l5mWe5h-dsuAZq8 🥝 Convert Python KivyMD App to Android .apk: kzbin.info/www/bejne/jKS3koBmapylmsU 🥝 Simple Python App with Kivy - Step by Step GUI Tutorial: kzbin.info/www/bejne/j3XTaGaNn7N8icU My next major project would be with kivymd (they actually just released new id designation commands for Python purists like myself 🤩). This project will include a step by step codealong, automation with Telenium and unittest/pytest, as well as deployment to several mediums (I've heard it can be adapted into a web app, I need to test is it works. BTW, the folks behind Kivymd are viewers of this channel, you'll see them once in a while in the comments 🙂

Excellent content! now i want to know more about SQL injection!

[@PythonSimplified]

Thank you so much! A few more viewers mentioning SQL Injection - and you got it! 😉 (it's so easy, you will never believe it!!!)

[@magowiz82]

Do I have to mention SQL injection to ask you to talk about SQL injection in another video about SQL injection? OK I mentioned three times, I hope it counts like this 😂

[@PythonSimplified]

@@magowiz82 hahahahaha now I must!! Don't worry, I am definitley filming this. It's highly unusual to see so many comments about something I've mentioned at the end of a 38 minute-long tutorial 🤪 I'll start working on it shortly, katching up with school in the next few days and then I'll move on with SQL Injection mad scientist simplified video 🙂

I have a Python code that use Tkinter to make a GUI. This code edit images. Now, I'm developing my webpage with Django, and I want to run the GUI code in my page. I hoped I could sove it with PYSCRIPT, but it's not compatible. I'm in a dead end. Can someone give me an advice?

Hey Mariya, love from India. Can you please make a tutorial of making a 3d realistic game in python?

[@anthoniG]

Was rather hoping it would be testing for QT (either PyQT or PySide)

[@LastdayPhysics3960]

Was is live? I missed it?

[@Sinke_100]

Mariya, I didn't download the code, but from watching the video when I see alot of elifs I wonder if perhaps is cleaner solution to it? def error_check(a, b, c): l = [a, b, c] l = [i for i in l if i] d = {0:'nothing provided', 1:'please enter one more side', 3:'you don\'t need me'} x = None if len(l) == 2 else d[len(l)] return x error = error_check('3', '3' , '') if not error: print('This is where you call another function that handles calculations') something like this perhaps

[@PythonSimplified]

Cleaner solution is always better! Fantastic refactoring, Sinisa!!! (As usual! 🤪) much appreciated! 😃

[@Sinke_100]

Now that I cloned and try your app, here is my solution: def callback(self, this_button): ''' a method executed each time the submit button is pressed ''' self.message.text = self.pythagorean() def pythagorean(self): a = self.input_a.text # leg b = self.input_b.text #leg c = self.input_c.text # hypotenuse x = len([i for i in (a,b,c) if i]) d = {0:"oops! no input was recieved! please enter 2 side lengths to get the 3rd!",1:"please enter one more side length to get the third!",2:False, 3:"if you already know ALL sides then you don't need me!"} if d[x]: return d[x] missing_index = [i for i,j in enumerate([a,b,c]) if not j][0] lh = lambda x,y: str((float(x)**2+float(y)**2)**(1/2)) ll = lambda x,y: str((float(y)**2-float(x)**2)**(1/2)) d = {0: lambda: ll(b,c),1:lambda: ll(a,c),2:lambda: lh(a,b)} return d[missing_index]()

Hi Mariya, what's up? Mariya, Could you tell me about how to build a gui program that locks an exe file with given password by user and when user attempts to enter that exe app, a form should ask for a password to enter that exe app? No matter, in which programming language is needed to do that So, plz give me your advice on how to build that kind of app

[@PythonSimplified]

I actually have the perfect set of tutorials for you! 😁 (it rarely happens!!! hahaha) To lock your setup file with a password (not .exe, but the actual setup wizard that leads to your .exe) you can follow this tutorial: ⭐ Convert GUI App to Real Program - Python to exe to setup wizard kzbin.info/www/bejne/pmTXhH-XqdJ6rLc then at minute 19:44 just set the password you'd like instead of leaving it blank. In addition, I highly recommend following the tutorial of the example GUI app we are converting. It uses a GUI library called Tkinter, which is very traditional and popular in Python. That way you can learn many principles of app making and then apply it on your own ideas. Here's a link: ⭐ Create GUI App with SQLite and Tkinter (Random Recipe Picker): kzbin.info/www/bejne/a6Kyn618bLemhKM Good luck and I hope it helps! 🙂🙂🙂

[@shakhnozahalilova3249]

@@PythonSimplified Yeah(Mariya), thanks. The interesting part of that is I've asked for it from a person who works at Facebook as senior software engineer, and he said, "It's kind of hard thing to do." And he also replied that, Because what you're actually requiring for requires good knowledge of assembly and other things to do

[@PythonSimplified]

Usually yes - but luckily I had a chance to simplify the entire process already! I've done the hard part so you guys don't need to deal with it on your end 😉 (Also, maybe share it with the Facebook guy if he doesn't like to deal with assembly 🤪 hahahaha)

[@shakhnozahalilova3249]

@@PythonSimplified yeah. Mariya, he's older than me and he has a family. I'm sixteen. And I asked for him "why not the most developers want to do this", and he replied me like "Not everyone want to do, because they have a their own job and they don't want spend their time on these kind of things". This so inspiring for me to make great effort to become such this great developer in the future.(I've never talked to such this kind of a person who is ready answer questions sincerely,people who are interested in programming or IT, generally)

[@PythonSimplified]

​@@shakhnozahalilova3249 senior developers tend to dismiss juniors with "read the manual" type of answers. They can explain it in 1 minute or send you on a long Google-search journey to maybe find an answer. I think it's silly and unprofessional, but then... I'm not a senior developer, so maybe it's an acquired quality 😅 hahahaha
