Tuples are a data structure used in Python to store an ordered collection of objects. When working with tuples, it might be handy to know how to quickly compute the mean. In this tutorial, we will look at how to get the average of a tuple with numeric values in Python.
How to find the average of a tuple in Python?
You can use a combination of the Python built-in sum() and len() functions to get the average of a tuple. Alternatively, you can also use methods from libraries like statistics, numpy, etc.
Let’s look at these methods with the help of some examples.
Using sum() and len() functions
To get the tuple mean, compute the tuple sum using the sum() function and divide it by the length of the tuple (which you can get using the len() function).
Here’s an example.
# create a tuple t = (10, 20, 30, 40) # get average of tuple values print(sum(t)/len(t))
Output:
25.0
We get the average of the tuple containing the values 10, 20, 30, and 40 as 25.
You can also compute the mean of a tuple directly using off-the-shelf methods from some libraries like statistics and numpy.

Using statistics library
You can use the statistics standard library’s mean() function to get the mean of a tuple. Pass the tuple as an argument to the function.
Here’s an example.
import statistics # create a tuple t = (10, 20, 30, 40) # get average of tuple values print(statistics.mean(t))
Output:
25
We get the same result as above.
For more on the statistics library, refer to its documentation.
Using numpy library
You can also use the numpy library to get the average of values in a tuple. Pass the tuple as an argument to the library’s mean() function.
Let’s look at an example.
import numpy as np # create a tuple t = (10, 20, 30, 40) # get average of tuple values print(np.mean(t))
Output:
25.0
We get 25 as the mean, the same result that we got with the methods above.
