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
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]
