In this tutorial, you will learn how to write a program to calculate mean value in pandas with example.

Pandas has inbuilt mean() function to calculate mean values. You can calculate for entire dataframe or single column also.

Syntax : DataFrame.mean(axis=None, skipna=None, level=None, numeric_only=None, **kwargs)

axis : {index (0), columns (1)}
skipna : boolean, default True

Exclude NA/null values when computing the result.

level : int or level name, default None

If the axis is a MultiIndex (hierarchical), count along a particular level, collapsing into a Series

numeric_only : boolean, default None

Include only float, int, boolean columns. If None, will attempt to use everything, then use only numeric data. Not implemented for Series.

import pandas as pd data = pd.DataFrame({ 'name':['ravi','david','raju','david','kumar','teju'], 'experience':[1,2,3,4,5,2], 'salary':[15000,20000,30000,45389,50000,20000], 'join_year' :[2017,2017,2018,2018,2019,2018] }) #To calculate total mean print(data.mean()) #to calculate mean for specific column print(data['salary'].mean())
