Arithmetic Operations in Numpy Arrays

Arithmetic Operations in Numpy

As we already know the arithmetic operations like addition, subtraction, division, modulo division, floor division, etc. in python. The same arithmetic operations can be performed in the Numpy arrays.

Create an Numpy arrays

import numpy as np
data1 = np.array([1,2,3])
data2 = np.array([4,5,6])        

Here, we create an arrays named 'data1' and 'data2' to perform arithmetic operations on it.

Addition in Numpy arrays

We can add two numpy arrays by using the symbol '+' is placed in between the two arrays.

Example

print("Addition :", data1 + data2)        

Output

Addition : [5 7 9]        

Subtraction in Numpy arrays

We can subtract two numpy arrays by using the symbol '-' is placed in between the two arrays.

Example

print("Subtraction :", data1 - data2)        

Output

Subtraction : [-3 -3 -3]        

Multiplication in Numpy arrays

We can multiply two numpy arrays by using the symbol '*' is placed in between the two arrays.

Example

print("Multiplication :", data1 * data2)        

Output

Multiplication : [ 4 10 18]        

Division in Numpy arrays

We can divide two numpy arrays by using the symbol '/' is placed in between the two arrays. It will return quotient as a result.

Example

print("Division :", data1 / data2)        

Output

Division : [0.25 0.4  0.5 ]        

Modulo Division in Numpy arrays

We can divide two numpy arrays by using the symbol '%' is placed in between the two arrays. It will return remainder as a result.

Example

print("Modulo Division :", data1 % data2)        

Output

Modulo Division : [1 2 3]        

Floor Division in Numpy arrays

We can divide two numpy arrays by using the symbol '//' is placed in between the two arrays. It will neglect the values after a decimal.

Example

print("Floor Division :", data1 // data2)        

Output

Floor Division : [0 0 0]        

Exponent in Numpy arrays

We can take exponent of two numpy arrays by using the symbol '**' is placed in between the two arrays.

Example

print("Exponent :", data1 ** data2)        

Output

Exponent : [  1  32 729]        

Challenge: Try out the all above operations in 2D array and see the output.
