Python: Exercises
2. Accessing list elements. In Python, you can access list elements by referencing their index value.
Consider the list a_list = [10, 20, 30, 40, 50]. To access the number 20 in the list, you would
use the syntax a_list[1]. Note that indexation starts at 0 in Python.
The list object, a_list has been defined for you. Do the following things to that list:
1. Print the 3rd element.
2. Change the 5th element to the list [0, 1].
3. Change the 2nd element to the empty list[].
a_list = [10, 20, 30, 40, 50]
# Print the 3rd element.
print(___)
# Set 5th element to list [0, 1].
a_list[4] = ___
# Set 2nd element to empty list: [].
___
# Print the 3rd element.
print(a_list[2])
# Set 5th element to list [0, 1].
a_list[4] = [0, 1]
# Set 2nd element to empty list: [].
a_list[1] = []
test_object("a_list")
success_msg("Excellent work.")
Remember that indexation starts at 0 in Python.
