Question 1:

We have a list of following:

zoo = ['monkeys', 'tigers', 'pandas', 'penguins', 'giraffes', 'hippos', 'bears']

how to retrieve a slice of list zoo, so you can get the following results?

['tigers', 'pandas', 'penguins', 'giraffes']
['hippos', 'bears']

Question 2：

Using split and join function of the list to change string

"green,red,yellow,blue,"

into string:

"green light* red light* yellow light* blue light* "

Hint:

>>> vegetables = "carrots, potatoes, onions, leeks, celery"
>>> # string.split(separator) will split the string by separator, for example:
>>> vegetables = vegetables.split(", ")
>>> print(vegetables) 
['carrots', 'potatoes', 'onions', 'leeks', 'celery']

>>> # string.join(list) will use string to connect every string item in the list, for example:
>>> fruits = ["avocados", "bananas", "oranges", "grapes", "mangoes"]
>>> ", ".join(fruit)
>>> 'avocados, bananas, oranges, grapes, mangoes'
