Python Program to Perform Arithmetic Operations on Array

The Python Numpy module has the add, subtract, multiply, divide, mod, and remainder functions to perform the Arithmetic Operations on Numpy Array and the below program shows the same.

# Array Arithemetic Operations
import numpy as np

optarr1 = np.array([10, 20, 30, 40, 50])
optarr2 = np.array([5, 25, 4, 15, 4])

addarr = np.add(optarr1, optarr2)
subarr = np.subtract(optarr1, optarr2)
multarr = np.multiply(optarr1, optarr2)
modarr = np.mod(optarr1, optarr2)
remainderarr = np.remainder(optarr1, optarr2)
divarr = np.divide(optarr1, optarr2)

print("**The Array Items After Perfroming Arithmetic Operations ***")
print("Array Addition = ", addarr)
print("Array Subtraction = ", subarr)
print("Array Multiplication =  ", multarr)
print("Array Modulus = ", modarr)
print("Array Remainder = ", remainderarr)
print("Array division = ", divarr)

In this Python Program, we use the Arithmetic operators to Perform the Arithmetic Operations on Numpy Array.

# Array Arithemetic Operations
import numpy as np

optarr1 = np.array([10, 25, 35, 45, 50, 70, 90])
optarr2 = np.array([5, 40, 65, 7, 19, 22, 11])

addarr = optarr1 + optarr2
subarr = optarr1 - optarr2
multarr = optarr1 * optarr2
modarr = optarr1 % optarr2
divarr = optarr1 / optarr2

print("**The Array Items After Perfroming Arithmetic Operations ***")
print("Array Addition = ", addarr)
print("Array Subtraction = ", subarr)
print("Array Multiplication =  ", multarr)
print("Array Modulus = ", modarr)
print("Array division = ", divarr)

**The Array Items After Perfroming Arithmetic Operations ***
Array Addition =  [ 15  65 100  52  69  92 101]
Array Subtraction =  [  5 -15 -30  38  31  48  79]
Array Multiplication =   [  50 1000 2275  315  950 1540  990]
Array Modulus =  [ 0 25 35  3 12  4  2]
Array division =  [2.         0.625      0.53846154 6.42857143 2.63157895 3.18181818
 8.18181818]

The below Program will Perform Arithmetic Operations on Array using the For loop.

# Array Arithemetic Operations
import numpy as np

optarr1 = np.array([10, 25, 35, 45, 50, 70, 90])
optarr2 = np.array([5, 40, 65, 7, 19, 22, 11])
addarr = np.empty(7)
subarr = np.empty(7)
multarr = np.empty(7)
modarr = np.empty(7)
divarr = np.empty(7)

for i in range(len(optarr1)):
    addarr[i] = optarr1[i] + optarr2[i]
    subarr[i] = optarr1[i] - optarr2[i]
    multarr[i] = optarr1[i] * optarr2[i]
    modarr[i] = optarr1[i] % optarr2[i]
    divarr[i] = optarr1[i] / optarr2[i]

print("**The Array Items After Perfroming Arithmetic Operations ***")
print("Array Addition = ", addarr)
print("Array Subtraction = ", subarr)
print("Array Multiplication =  ", multarr)
print("Array Modulus = ", modarr)
print("Array division = ", divarr)
