- Amend your looking method to create a single string representing the animals and birds in the zoo. Hint: create a static method that accepts the concatenated list of animal list and bird list and uses the reduce and map functions with the lambda function to get the look method for each item in the concatenated list.
- Add one method (called find_canine ) into the zoo class to find all the canines in the zoo. This method can use a filter function with lambda function to check if the item object in the animal list has the same instance as Canine and return a list that can pass to the static method built in Point 2 to return a string representation of that object.
- Add one method (called find_tiger) into the zoo class to filter out tigers in the zoo and look at them. This method can use a filter function with re.search and map and lambda functions to achieve this functionality. Hint: you will have to go over all the animals in the zoo.

I try to add all methods but it didn't work.
