Hello Sir. why after saving the array as new array which was after deleting, when you loaded it, it was again like before deleting . shouldnt it be with the changes you made which is deleting the first column? thank you so much
When he deleted part of the array, he never saved that new edited array to the original array variable, which means the original array stays the same after the deletion method.
Sir could you once confirm @15:51 about the axis in this video ? (I think axis=0 for row and axis=1 for column) just a small confusion. Everything else helped me to revise quick. Thanks :)
@@ihsanpro9406 Also I would like to add that Pandas on the lower level is built on top of numpy itself, same goes for sklearn, etc... So we can say that numpy is the building block on data science ecosystem in python... and in a single word - numpy is used for linear algebra. [most imp math concept for statistics and data science]
It's good for all kinds of matrix operations. Basically you can do everything that Matlab can do (without Simulink) with just Numpy, Scipy, sklearn and matplotlib. If you're a mechanical engineer, a physician etc etc it makes a lot of sense to use Numpy. For Software Engineering...you bump into Numpy more rarely.
Please I'm totally new to numPy. Could someone kindly explain what the numbers in the parenthesis connote for the 4 different types of array created at the beginning of the video. For instance, np.random.rand(2,3,4) what does the 2,3,4 stand for? Because I was expecting random arrays containing just those numbers but that is apparently not the case
@@NicholasRenotte A little late to the party but a real world problem video and steps on how to solve it could be interesting! I'm just learning Python and I'm having a hard time finding projects to do to practice my skills.
Awesome stuff @@guillaumelaprotte5487, I've got some beginner friendly AI/ML tutorials. Check these two out: ruclips.net/video/8k8S5ruFAUs/видео.html and ruclips.net/video/T9KfYaS9hwQ/видео.html
It would have been helpful to first go into what the dimensions of the array represent before jumping into reading arrays? Also, on another channel today I learned lists are not the same as arrays.
This video really helped me get a grasp on the difference between lists and arrays - not entirely because it was explained but because I had to pause and do research. I understood that lists could store data of different types and arrays stored data of exactly one type, what I didn't know was that the size of a list can be changed dynamically and the size of an array is fixed. This is why when we perform manipulations to an array like np.delete() we set the function equal to the name of the array. We're not modifying the array but creating a new one and assigning it to the same variable.
This is so clear and concise. I started a asynchronous numpy class nd had no idea where to start. This helped a LOT.Thank you so much!
Short, specific and to the point. Great, keep going 👏👍
Thanks so much @Muhmmed!
Fast & clear explanation Ta, நன்றி ...
Clear and Objective. Nice video. It was great to review the NumPy library.
I totally understand your lessons . Thank you!!
Thanks.. Was having a hard time with a course.
😅😎I am from somaila in somaliland thank you for creating this amazing tutorial congratulation nicholas renotte
Isn't "SLAP ME" more hilarious? Thank you for the video! 🤭😉
Thank you so much sir for making this video. 🙏🏻🙏🏻🙏🏻

@@haze13_ thank you for your kind reply
Where can i find the notebook you're working on ?
Well Explained, Very Insightful
Thank you Nichola :'')

Yep, you're correct 0 is for row 1 is for column
I also googled this. Is there a name yet for asking chatgpt something? bc I guess I don't google anymore so much as I consult chatgpt...
Very helpful. Thank you.
Why we need to use Numpy? To solve what issue?
Because its much better for calculating metrics / statistics / better way to organize your list and it is faster as it is underpinned by c itself

@@mahanirvaantantra thanks for the insight. I’m fairly new to coding but that’s what I understood.

Because I was expecting random arrays containing just those numbers but that is apparently not the case
This means a 3-D array where 2 means 2 subarrays, 3 means 3 rows and 4 means 4 columns. So 2 subarrays each having dimension of 3x4.
Great quality sir, thank you
😁 thanks @Nabil Mercheri! Any other vids you’d like to see?!

Thank you.
Sqrt, power, log, etc. are not statistical functions; they mathematical functions.
