Use different slicing techniques to extract the names of animals from strings of text

This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.

The syntax of slicing is shown by this example:

# an example to start us off

print("So have we spun"[0::3])

This would print out the word Sheep (it would take the characters beginning at the first one, going on to the last one and picking out every 3rd character).

Using the same sort of syntax, see if you can find these animals:

Print the first 3 letters of the word catastrophe.
Print letters 4 to 6 from The Dogs of War.
Print the last 3 letters from The Trouble with Lichen.
Print every other character from Springy, beginning at the second.
Print every other character from meagre, starting with the penultimate one and going backwards.

You can use -1 to refer to the last character, -2 to refer to the penultimate character, etc, and use a negative step value to go backwards rather than forwards in your text.

Save your complete program as Old McDonald.py, then close it down.

You can unzip this file to see the answers to this exercise, although please remember this is for your personal use only.
