Find the Mean of a List in Python

  • Post category:List

Finding the mean (average) of a list in Python can be done by using the statistics module or manually calculating the sum and dividing by the length of the list. Here are two examples:

Example 1:

import statistics

numbers = [1, 2, 3, 4, 5]
mean = statistics.mean(numbers)
print(f"The mean of the list is: {mean}")

Output:

The mean of the list is: 3

Example 2:

grades = [85, 90, 92, 88, 95]
mean = sum(grades) / len(grades)
print(f"The mean grade is: {mean}")

Output:

The mean grade is: 90.0
