how to get size of list in python

1studentGrades = [9.1, 8.8, 10.0, 7.7, 6.8, 8.0, 10.0, 8.1, 10.0, 9.9]
2print(len(studentGrades))

1list1 = [1,2,3]
2print(len(list))

1list_1 = ["Hello", 1, "World", 2]
2# if you want length of this lins use len() function
3print(len(list_1))
4
5# if you want size in bytes
6import sys
7print(sys.getsizeof(list_1), "Bytes")

1my_list = [1,2,3,4,5,6,7,8,9,10]
2
3length_of_list = len(my_list)

1li = [None] * 5 # [None, None, None, None, None]
2li = [0] * 5 # [0, 0, 0, 0, 0]

1len(list)
