A list index behaves like any other variable name! It can be used to access as well as assign values.
You saw how to access a list index like this:
zoo_animals # Gets the value "pangolin"
You can see how assignment works on line 5:
zoo_animals = "hyena" # Changes "sloth" to "hyena"
Write an assignment statement that will replace the item that currently holds the value
"tiger" with another animal (as a string). It can be any animal you like.
