Pythonにおける平均値の計算方法の基礎と応用

1my_list = [1, 2, 3, 4, 5]
2average = sum(my_list) / len(my_list)
3print(average)  # Output: 3.0

1import statistics
2
3my_list = [1, 2, 3, 4, 5]
4average = statistics.mean(my_list)
5print(average)  # Output: 3

1import numpy as np
2
3my_array = np.array([1, 2, 3, 4, 5])
4average = np.mean(my_array)
5print(average)  # Output: 3.0

1class Person:
2    def __init__(self, age):
3        self.age = age

5people = [Person(10), Person(20), Person(30), Person(40), Person(50)]
6average_age = sum(map(lambda p: p.age, people)) / len(people)
7print(average_age)  # Output: 30.0
