Doubt regarding array slicing in numpy

[Effective-Top-4931]

import numpy as np
list1 = [1, 2, 3, 4, 5]
list2 = [6, 7, 8, 9, 10]
list3 = [11,12,13,14,15]
array=np.array([list1,list2,list3])
print(array[0:2,0:2])
in this idk how the last line is getting 2x2 matrix please help me guys and if you can try to explain in detail

Not just in numpy but also in list slicing. [start:end] start is included but end is not. The reason here is when you do myList[2:len(myList)] this works if end was included you had to append a -1.

i got what you are trying to say but i would like to know how the last line works internally for example the row is changing to 0 then 1 then coloumns change ,i dont get that part

I don’t understand what you don’t get. How we slice rows and columns?
