<!-- language: lang-html -->

    sample_list = [2, 10, 3, 5]

    sample_listSum =[sample_list[0]+ sample_list[1]+ sample_list[2]+ sample_list[3]]

    sample_listLength = len(sample_list)

    sample_listAvrage = sample_listSum / sample_listLength

    print("This is result of list", sample_listAvrage)

<!-- end snippet -->
