How to get the size of a list in Python?

In Python, the list type is a built-in data structure used for storing multiple elements. You can use the len() function to get the number of elements in the list, which is also known as the size or length of the list.

Here is a more detailed example code:

# 创建一个包含多个元素的列表
my_list = [10, 20, 30, 40, 50]

# 使用len()函数获取列表的大小
list_size = len(my_list)

# 打印列表的大小
print("列表的大小为:", list_size)

In this example, a list called my_list containing 5 integers is first created. Then the size of the list is obtained using the len() function, and the value is assigned to the variable list_size. Finally, the size of the list, which is the number of elements in it, is printed out.
