Answer the following:

3. Brainstorm how you would print the first element from a_list.

In your console, type the following:

    a_list = ['a', 'b', 'c', 'd', 'e']
    print(a_list[0])
    print(a_list[1])
    print(a_list[2])
    print(a_list[3])
    print(a_list[4])
    print(a_list[5])
    print(a_list[6])
