I never thought understanding the prerequisite of machine learning is that much easy and Krish sir you make it alot easier.

[archanaashok]

Hi Krish, Python is made so simple to learn from you. Always had difficulty in understanding and remembering from other tutors. Never felt it so easy and enjoyable to learn. Thank you for your efforts.

arr[1:3, 2:4] = array([[4, 5],
[6, 8]]) Thank you Krish! I am following your path to become a Data scientist

[gulabmeetyou]

EAGERLY EXPECTING Scikit learn and PLOTLY tutorials. No one has taught about Plotly... If you make this it would be great....

[ShivamSingh-kngz]

For the subarray 4, 5, 6, 8 code is:
arr[1:, 2: 4]
For the subarray 3, 4, 5 code is:
arr[1, 1: 4].
I started your session, sir, really your contents are truly valuable. Thanks for making this all happen. I wanna learn as best as possible about the concept of Machine Learning.
Really glad that I found your channel at the time when I was in its complete need.
Thank you soo much, sir

Thank you Krish Naik for teaching us by this much of patience. You have cleared so many of my doubts.

[farazahmed]

His explanation is clear and everything is practical.

[xeno_plays]

For accessing 4, 5, 6, 8 answer is arr[1:, 2:4] and for accessing 3, 4, 5 answer will be arr[1:2, 1:4]

[BHANU]

Following are taught in video:
-Array definition

- Array indexing
- Array Range
- Array linspace
- Array copy and broadcasting
- some functions in Array like np.ones, np.random.rand (random distribution), np.random.randn (normal distribution), np.random.randint etc.

Goat of Python bro, learned 3 months work in 3 lectures.

[sharvandas]

*Numpy *Array
1.Creating One Dimensional array.
2.Creating Two Dimensional array.
3.Shape, reshape and indexing(slicing) done in two dimensional.
4.In-built function present in numpy- arange, linspace, ones, random.(and more)
5.Concept of copy and Exploratory data analysis
Please share the list built-in functions of numpy. Thanks
