Bàn luận
Đưa ra một danh sách. Nhiệm vụ là tìm tổng và trung bình của danh sách. Trung bình của danh sách được định nghĩa là tổng của các phần tử chia cho số lượng các phần tử.
Example:
Python3
Phương pháp 1: Phương pháp ngây thơ
Trong phương pháp này, chúng tôi sẽ lặp lại trong danh sách và sẽ thêm từng phần tử vào một số biến lưu trữ tổng của phần tử ITH và sau đó chia tổng với tổng số biến để tìm mức trung bình.

Làm thế nào để bạn tìm thấy mức trung bình trong Python?
Trung bình Python trung bình trong Python thường được tính bằng cách thêm tất cả các số trong một danh sách và sau đó chia nó cho số lượng các phần tử trong danh sách này.adding all the numbers in a list and then dividing it by the number of elements in this list.
Làm thế nào để bạn tìm thấy tổng trung bình?
Trung bình Đây là giá trị trung bình số học và được tính toán bằng cách thêm một nhóm số và sau đó chia cho số lượng của các số đó.Ví dụ, trung bình của 2, 3, 3, 5, 7 và 10 là 30 chia cho 6, là 5.adding a group of numbers and then dividing by the count of those numbers. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.
Có tổng số chức năng trong Python không?
Python cung cấp một tổng số hàm sẵn [] tổng hợp các số trong danh sách.Cú pháp: Sum [có thể lặp lại, bắt đầu] có thể sử dụng được: Có thể là bất cứ thứ gì danh sách, bộ dữ liệu hoặc từ điển, nhưng quan trọng nhất là nó phải là số. which sums up the numbers in the list. Syntax: sum[iterable, start] iterable : iterable can be anything list , tuples or dictionaries , but most importantly it should be numbers.
