1. how to create array using numpy :

import numpy as np
#ad array

a=np.array([10,20,30]) // int,float ,String  // array should be homoginous

#2 d array 3*3

b=np.array([
[1,2,12],
[12,12,12],
[12,34,5]
])

#3*3*3

c=np.array([

[[1,2,3],[4,5,6],[7,8,9]],
[[4,5,6],[8,6,7],[5,6,7]],
[[8,8,8],[9,9,9],[9,98,8]]
])

print(a)
print(b)
print(c)


#Arrange Function :

a = np.arange(10,20) //start value and end value
print(a)
[10........................19]

a=np.arnage(10,20,2)
