sciPy stats.itemfreq() function | Python

scipy.stats.itemfreq(arr, axis = None) function helps us to calculate the item frequencies. 

Parameters :
arr : [array_like] input array. 
Results : 2D array with item frequency. 

Code #1: Use of variation()  

Python3

# cumulative frequency
from scipy import stats
import numpy as np

arr = [14, 31, 27, 27, 31, 13, 14, 13]

print ("Itemfrequency : \n", stats.itemfreq(arr))

print ("\n\nBincount : \n", np.bincount(arr))

Output:

Itemfrequency : 
 [[13  2]
 [14  2]
 [27  2]
 [31  2]]


Bincount : 
 [0 0 0 0 0 0 0 0 0 0 0 0 0 2 2 0 0 0 0 0 0 0 0 0 0 0 0 2 0 0 0 2]
