How to calculate the frequency of each item in a Pandas series?
In this program, we will calculate the frequency of each element in a Pandas series. The function value_counts() in the pandas library helps us to find the frequency of elements.
Algorithm
Step 1: Define a Pandas series. Step 2: Print the frequency of each item using the value_counts() function.
Example Code
import pandas as pd series = pd.Series([10,10,20,30,40,30,50,10,60,50,50]) print("Series:\n", series) frequency = series.value_counts() print("\nFrequency of elements:\n", frequency)
Output
Series: 0 10 1 10 2 20 3 30 4 40 5 30 6 50 7 10 8 60 9 50 10 50 dtype: int64 Frequency of elements: 50 3 10 3 30 2 20 1 40 1 60 1 dtype: int64
