Question

Write a program to create a random 1D NumPy array with five elements. Now find the nearest value from a user given value in a NumPy array. Sample output: 4.96138509939

Answer 1

import numpy as np                                  #importing numpy library
array=np.random.rand(5)                  #random.rand() is used to take random values.
print("random numpy array is",array)
print("Enter a number = ")
n=input()                                 # Taking input from the user
n=float(n)
temp=abs(array[0]-n)       # abs() function is used to find the absolute value(i.e., positive value) of a number
for i in array:         # loop iterates taking each array element as i in each iteration.
    diff=abs(i-n)         # to check how much the number nearer to given number
    if diff < temp :
        temp = diff
        near=i;
print("nearest value to given number in the array is = ",near)

output :
