If __name__ == "__main__" for Python Developers

If name equals main - then we run our programs!
But do we actually understand what is _name_ , what is _main_ and most of all - why do we need to check if they match? 🤔🤔🤔
I've prepared this very special tutorial that dives deep into each component and demonstrates it thorough simple code examples. By the end of this video - you'll be able to explain this expression in your own words (!!!) as well as other terms like "module" and even "top level code" 😉
⏰ TIME STAMPS ⏰

I like it when youtubers describe their code(s) verbally as they go along. For a blind person such as myself, it is of great help, since screen readers normally don't speak the contents inside videos, only in their descriptions, so if you say what you are doing while you write/show the code, the explanation becomes accessible! Thanks and keep up the good work!

[@WhiteNight0204]

Please don't take this question as offensive, as I am only intrigued, but you program while being blind? Is it actually doable?

[@RAP4EVERMRC96]

@@WhiteNight0204 I am not an expert in accessibility features, but I remember from my time at apple that on a regular blind or visually impaired people would come in to give their Mac to service. They were able to fully control their computer due to the accessibility features and additionally there were experts in the store that knew how to use these features. So I guess as long as you can control a computer you can program on it.

[@supermalavox]

@@RAP4EVERMRC96, thanks for the help in replying! I will add that while blind people might not be the greatest in GUIs in terms of object positioning, colors, etc, we can definitely build working functions and even deal with oop. Also, the screen reader that comes with Linux/GNOME - Orca - and one we use on Windows - NVDA - are both programmed in python! And as far as I know, NVDA's original developer - Mick Curran - is blind. I myself am not a professional programmer, but like to learn something on Codewars, Exercism, etc.

Rock on, my guy. You are an inspiration.

[@michalbotor]

you've achieved mastery in clean, logical, and engaging explanations of programming concepts. my understanding of the topic has increased substantially. thanks so much mariya!

[@EmaMazzi76]

Your lessons Mariya really worth every seconds spent…watched dozens of videos regarding this topic (if __name__ == “__main__”…) and for the very first time I understand what it does actually 😄 thank you, thank you, thank you

[@PythonSimplified]

Yeeeeeeyyy Emanuele, I'm so happy to hear that!!! 😀 For a very long time I understood the general concept, but after making this tutorial - you can wake me up in the middle of the night with a surprise quiz - and besides me being a bit grumpy I'll probably get an A+! hahahaha 🤣🤣🤣 Anyhow, I really enjoyed making this one and super glad you found it useful! 😊

[@MrKrtek00]

This was actually way more insightful than I expected... Thanks, great explanation!

[@trong-tintran6262]

I am a French developer, beginner in python, and your tutorial is extremely clear, I understood everything! I often avoid English tutorials because the KZbinr speaks quickly and I have trouble following but here I have nothing to complain about, your English is simple and easy to understand. I subscribe to your channel +1. Thank you very much for this wonderful work. This is the first time I've posted a message on KZbin in my entire life 😂 but it's well deserved !👏🙏

[@ssloc]

So thorough with great examples/visuals! Great job 👏. I look forward to more.

[@MrIsaacpr7]

I’m really enjoying your videos a lot. I’ve been wondering why I write that exact line of code for weeks, with no clue as to why. Once again, you nailed it! Your way of explaining things in a digestible manner for a total beginner is unparalleled. Thank you for sharing.

[@Richie.P71]

I have been wondering this for ages, thank you for breaking it down so simply. You are the best!!

Thank you Richie! I'm super happy you found it helpful! 😀

[@portinho199]

As always, the best and cleary explanation from entire KZbin platform. Thank you so much!!!

[@deniskasala8520]

I used to scroll down and pass your videos but now i am hooked as your methods of teaching is really easy. Thanks again

[@ad.chacon]

I just clicked this video bc I started learning Python yesterday, I have never seen a if __name__ = "__main__" in my life, yet you managed to make me understand how this works and why is it this way.

[@NoOne-L]

Wow! Your channel was recommended to me a few months back and I kept passing it. Glad I finally watched 1 of your video. You’re such a great teacher. You make complex stuff simple. Thanks and will watch more videos from you

[@bigbadcatbigbcy2933]

lol same

[@mirandaenergypark5271]

Excellent explanation! You have included some essential features of this statement that makes it all so much more understandable, unlike many other explanations I have seen on KZbin. Thanks!

[@jcmschott1895]

Amazing content! Pleeease keep it up! You built it up like a crescendo and suddenly became crystal clear why this "if __name == __main__:" stuff is so necessary.

[@PARTner91]

If only everyone could explain things as clearly as you do. Nice job, thank you.

[@arthurbosquetti]

This was such a good video! I've always been curious about this, but never really looked it up. Now it makes sense :) Thanks for the clear explanation!

[@lukajeliciclux3074]

So much quality in this video. Simply perfection. Even thought I know a lot about if __name__ == '__main__' I found an additional information I've never know.

[@asmitaghorai7332]

Yeeeyyyyyy! Thank you so much for the incredible feedback, hiutale!! 😁😁😁 I always enjoy reading your comments and I'm super happy you find my videos useful! A few more Python projects to experiment with - and you'll be able to ditch the beginner status in no time 😉

[@ClaudiaWick]

excellent explanation! I already tried for longtime to understand the basics of this statement, not only demonstrations of what happens with or without it. Thank you to spend more time than others to explain this for beginners: it is really helpful!

[@hawardjoseph2201]

Your explanation is super great!!! I haven't anywhere seen such a great explanation, in my mind makes your teachings remember quite easy. Thank you so much and please continue making more and more videos for the world.

this is by far the most professional guide I've seen on this topic. this girl is serious

[@hondacars8444]

Great video. Thorough yet succinctly presented. Awesome job 👍🏻

[@michaeltheisen]

The example at the very end with "from import_me import call_me" that showed it running the function just because it was imported, really helped me solidify the concept. Thank you! And thank you for all your quick videos on good python habits and explanations like this. They really do help us get through some of our projects after we've been out of the game for so long.

[@bobursuyunov00]

[@renatomachelett]

​@@PythonSimplified I'm really happy that I got the opportunity to point it out! ☺ Much of the time, people just consume without considering the energy that is necessary to create something excellent. Whenever I notice the lengths that someone must have gone to in creating something exceptional, instead of giving in to mediocrity, I try to let them know that I know. It needs to be said and more people need to say it! So, once again, thank you very much for the wonderful product of your exemplary work ethic! 👏🙏
