Arrays

What is the dimension

You can find the dimension of the array, whether it is a two-dimensional array or a single dimensional array.

a = np.array([(1,2,3),(4,5,6)]) 
print(a.ndim) 

Size of each element

a = np.array([(1,2,3)]) 
print(a.itemsize) 

The data type of the elements

a = np.array([(1,2,3)]) 
print(a.dtype) 

Reshaping

a = np.array([(8,9,10),(11,12,13)]) 
print(a) 
a=a.reshape(3,2) 
print(a) 

Slicing

a=np.array([(1,2,3,4),(3,4,5,6)]) 
print(a[0,2]) 
print(a[0:,2]) 

a=np.array([(8,9),(10,11),(12,13)]) 
print(a[0:2,1])
