Python: Modules and Packages

[@moorelo]

Thank you for explaining modules so clearly. I starting programming in FORTRAN IV in the 80s, Python has me excited about programming again.

[@RaynerDaCruz]

@9:20 Wouldn't the first snippet of code result in a ModuleNotFoundError since point-call.Point() is not prefixed with Drawing? Like this, Drawing.point-call.Point()?

[@wiliextreme]

thanks for this great video, coming from nodejs I found it pretty confusing how python imports work but now I get it

[@ryansossou646]

Hey Damian, this is exactly what I was looking for, I just started working on a big project with python but package and modules management was really confused, now everything is clear, you're the best Damian, thanks for bringing those free resources for the community

[@ratonmagico]

This video is gold. Best explanation on modules and packages I've found in KZbin.

[@HtorneDK]

what an EXCELLENT video - this content is beyond any other tutorials on the web. omg this is good. Instant subscribe. Thanks

[@MoistKing]

Thankyou for the great lecture! Love the "Banana" examples.

[@AhmedAli-dz1hy]

He is full of information. Better than professors

[@dbmaster46446]

is following code the right way to use __init__ ? im still not sure how i should construct packages for module in os.listdir(os.path.dirname(__file__)): if module.startswith("__"): continue name = "{}.{}".format(__name__,module) if not module.endswith('.py') else "{}.{}".format(__name__,module[:-3]) __import__( name) del module

Perfect

[@EasyLanguageCoach]

Very well done. A good explanation of it. Thank you very much.

[@feniordi]

Simple explenation and good examples, thanks for the tutorial!

[@cybervigilante]

Wow, that cross-importing is cool. And it doesn't even have to be a class. I tried it on a simple function.

[@AhmedAli-dz1hy]

That is great. Like these slides and like your easy way of explanation

[@scienceblossom6197]

What if we want to import more than a module from a sub-directory? E.g. what if we want to import all the methods in a module in a subdirectory(e.g. ./childDir1/module ---> contains 10 methods)

[@damiantgordon]

With new Python this should work >>> from import *

[@haopeiyang3443]

Thank you for this video Mr. Gordon. The content is solid.

Say near the Maths, there's Biology folder, which has Calculations.py. How does one import Theorem.py into it? [...] |---Maths |--- --- __init.py |--- --- Theorem.py |---Biology |--- --- __init.py |--- --- Calculations.py

[@Brandon-hb7tx]

yomajo from Drawing.Maths import Theorem I would think

How do i import a file but not run it?Just so i can use the variables??

[@damiantgordon]

Are they in a class in the file?

@@damiantgordon I want to get input that is saved in a file login.txt in the module register and then read it in module login.So obviously i want to run module 1 but by running module 1 not by importing it to module2(if that makes sense).And then read the input from module 1 but in module 2.

[@سفيانقريميدة]

Excellent explanation, thank you very much

[@ettercap5384]

How do I import the .py that is in the main folder and not in the subdirectory?

[@damiantgordon]

Just say "Import FileName"

[@djamelfertas]

Wow that's such an amazing explanation, Thank you Sir

[@ProfessionalTycoons]

I use this all the time, but never knew whats going on behind the scene lol

[@beratakuzum8381]

Amazing and detailed tutorial. Thank you so much!

[@Adks007]

Very nice video. Respect from United states

[@dileepaozi2352]

Wow nicely explained... can you do a video like this about distribution of python program to users, things like setup.py, python egg, pyInstaller.

[@Mortum_Rex]

Did anyone else keep thinking Damian was holding a cane the whole time in his remote hand? He'd look pretty badass with a cane I reckon. Anyway, brilliant lecture! Thank you, sir.

[@dishonmwabashfano3627]

Thanks a lot. You are the best.

[@niyagentleman8143]

x-llent explanations! thanks so much for this tutorial! ^^

[@likysquad]

Geez, this is annoying, I can't compile my payload now because I've been using sys this whole time to duct tape the issue. My .py code is scattered all throughout my computer in different folders. Now I see I got a lot of learning to do. Thanks for the lecture.

[@PwrTrumper]

great video, fantastic explanation. I still think this whole __init__ idea is an unintuitive design choice in python.

[@sfcoawol6273]

Thanks for this lecture! I've been trying to import code from other files but I was having issues with referenceing variables from outside the code snippet into the code. Most guides are way to basic to explain this

[@Pedritox0953]

Great video!

[@shivamchaudhary470]

thank you sir

[@seghairtarek4629]

the best video ever thank you... you helped me a lot ^_^

[@mikerihm]

This is fantastic

[@PihFrags]

Very nice presentation Thank you for great content. One thing i noticed though was that you used uppercase names for packages. PEP 8 says points that lowercase should be used 😉But still. Structure and code was readable so still A+ for presentation

[@richiekho1159]

It is well explained, just that the sound need to be improveed

[@motherofako]

Wow sir , you are brilliant!

clean explanation.
