Python simple project using Numpy

Numpy : 

1. Creating numpy 

2. Finding dimension, data type, shape,  reshape 

3. Creating numpy with different way

4. Applying mathematics 

5. Compared two array 

6. Aggregate function 

7. Array manipulations -- concatenate two array, stack array vstack and hstack, split two array

8. Sorting array

import numpy as np 

a = np.array([1,2,3,4])

b = np. array([5,6,7,8])

print(a.size)

print("\n")

print(a.ndim)

print("\n")

print(a.dtype)

print("\n")

print(a.shape)

print("\n")

print(np.linspace(1,10,2))

print("\n")

print(np.arange(1,10,2))

print("\n")

x = np.logspace(1,10,2)

print(x)

print("\n")

print(np.zeros((4,2)))

print("\n")

print(np.ones((4,2)))

print("\n")

print(np.full((4,2),4))

print("\n")

print(np.random.rand(2,4))

print("\n")

print(np.sum([a,b],axis=0))

print("\n")

print(np.subtract(a,b))

print("\n")

print(np.multiply(a,b))

print(np.divide(a,b))

print("\n")

print(np.sin(a))

print("\n")

print(np.cos(a))

print("\n")

print(np.sqrt(a))

print("\n")

print(np.exp(a))

print("\n")

print(np.log(a))

print("\n")

print(np.array_equal(a,b))

print("\n")

print(np.equal(a,b))

print(np.min(a))

print("\n")

print(np.median(a))

print("\n")

print(np.mean(a))

print("\n")

print(np.std(a))

print("\n")

print(np.corrcoef(a))

print("\n")

print(np.concatenate((a,b),axis =0))

print("\n")

print(np.stack((a,b)))

print("\n")

print(np.vstack((a, b)))

print("\n")

print(np.hstack((a, b)))

print("\n")

print(np.split(a,4,0))

c = np.sort(a)[::-1]

        OR 

c = -np.sort(-a)

print(c)

Sort 2D array 

x = np. array([[1,2,3],[4,5,6]])

y = -np.sort(-x)

print(y)
