What is the output? for i in range(2, 8, 3): print("The value of i is currently", i)

The value of i is currently 2 The value of i is currently 5 starting stop step 2 (starting number) → 5 (2 increment by 3 equals 5 - the number is within the range from 2 to 8) → 8 (5 increment by 3 equals 8 - the number is not within the range from 2 to 8, because the stop parameter is not included in the sequence of numbers generated by the function.)

[0, 1, 8, 27, 64]

What is the output? my_list = [10, 8, 6, 4, 2] new_list = my_list[:] print(new_list)

[10, 8, 6, 4, 2] As we've said before, omitting both start and end makes a copy of the whole list:

What is the output? my_list = [10, 8, 6, 4, 2] new_list = my_list[:3] print(new_list)

[10, 8, 6] If you omit the start in your slice, it is assumed that you want to get a slice beginning at the element with index 0.

What is the output? my_list = [10, 8, 6, 4, 2] new_list = my_list[3:] print(new_list)

[4, 2]

What is the output? colors = { "white": (255, 255, 255), "grey": (128, 128, 128), "red": (255, 0, 0), "green": (0, 128, 0) } for col, rgb in colors.items(): print(col, ":", rgb)
