NumPy: Count the frequency of unique values in numpy array
NumPy: Array Object Exercise-94 with Solution
Write a NumPy program to count the frequency of unique values in numpy array.
Pictorial Presentation:

Sample Solution:
Python Code:
import numpy as np
a = np.array( [10,10,20,10,20,20,20,30, 30,50,40,40] )
print("Original array:")
print(a)
unique_elements, counts_elements = np.unique(a, return_counts=True)
print("Frequency of unique values of the said array:")
print(np.asarray((unique_elements, counts_elements)))
Sample Output:
Original array: [10 10 20 10 20 20 20 30 30 50 40 40] Frequency of unique values of the said array: [[10 20 30 40 50] [ 3 4 2 2 1]]
