##### How to perform array manipulation using Numpy?
###### Description

To perform array manipulation using numpy.

#### Input

Array of data. (Iris data)

#### Output

Array manipulation results.

###### Process

Create two array.

Do arithmetic operations of an array using Numpy.

Print the results.

###### Sapmle Code

#import libraries
import pandas as pd
import numpy as np

#load the sample data from csv file

#convert as a data frame
df = pd.DataFrame(data)

a = np.array(df.iloc[:,2])
b = np.array(df.iloc[:,3])

print(“First array\n\n”,a,”\n”)
print(“Second array\n\n”,b,”\n”)

#Array manipulation operation

print(“Trainspose array\n”)
c = np.transpose(b)
print(c.T,”\n”)

print(“Changing array shape\n\n”)
print(b.reshape(3,-2),”\n”)

print(np.append(a,b),”\n”)
print(np.insert(a,1,5),”\n”)
print(np.delete(a,),”\n”)

print(“Combining arrays\n\n”)
print(np.concatenate((a,c),axis=0),”\n”)

print(“Splitting the array (Horizontally)\n\n”)
print(np.hsplit(a,3),”\n”)

print(“Splitting the array (Vertical)\n\n”)
print(np.hsplit(a,3),”\n”)
