Python | Pandas Series.mean()

Pandas series is a One-dimensional ndarray with axis labels. The labels need not be unique but must be a hashable type. The object supports both integer- and label-based indexing and provides a host of methods for performing operations involving the index. Pandas Series.mean() function return the mean of the underlying data in the given Series object.

Syntax: Series.mean(axis=None, skipna=None, level=None, numeric_only=None, **kwargs) Parameter : axis : Axis for the function to be applied on. skipna : Exclude NA/null values when computing the result. level : If the axis is a MultiIndex (hierarchical), count along a particular level, collapsing into a scalar. numeric_only : Include only float, int, boolean columns. **kwargs : Additional keyword arguments to be passed to the function. Returns : mean : scalar or Series (if level specified)

Example #1: Use Series.mean() function to find the mean of the underlying data in the given series object. Python3

# importing pandas as pd import pandas as pd # Creating the Series sr = pd.Series([10, 25, 3, 25, 24, 6]) # Create the Index index_ = ['Coca Cola', 'Sprite', 'Coke', 'Fanta', 'Dew', 'ThumbsUp'] # set the index sr.index = index_ # Print the series print(sr) 

Output : Now we will use Series.mean() function to find the mean of the given series object. Python3

# return the mean result = sr.mean() # Print the result print(result) 

Output : As we can see in the output, the Series.mean() function has successfully returned the mean of the given series object.   Example #2: Use Series.mean() function to find the mean of the underlying data in the given series object. The given series object also contains some missing values. Python3

# importing pandas as pd import pandas as pd # Creating the Series sr = pd.Series([19.5, 16.8, None, 22.78, 16.8, 20.124, None, 18.1002, 19.5]) # Print the series print(sr) 

Output : Now we will use Series.mean() function to find the mean of the given series object. we are going to skip all the missing values while calculating the mean. Python3

# return the mean # skip all the missing values result = sr.mean(skipna = True) # Print the result print(result) 

Output : As we can see in the output, the Series.mean() function has successfully returned the mean of the given series object.
