I need the solution of all below python question codes along with correct return.

# 2. Given two classes 'Animal' and 'DigestiveSystem, implement, using COMPOSITION the method 'eat_food' in the 'Animal' class.
# * Animal instances should have a 'diggestive_system' attribute, which is the DigestiveSystem instance of that object.
# * The eat_food method should PROCESS any 'food' (any string) that are not allergenic (use the method 'has_allergy' to check for this case)
# * The DigestiveSystem is a class responsible for the PROCESS of any food eaten,
# so make use of this in the Animal.eat_food method (remember COMPOSITION!)
class DigestiveSystem:
"""This class is already done for you
don't changea any code on it.

# 3. Rewrite the Human class bellow (without changing it's name), so that it inherits from the Animal class of the exercice 2.
# * You should override the 'has_allergy' method in the Human class, so that it now only returns True if the food is 'peanut'
class Human:
pass

# 4. Implement the Child class below, which inherets from Human (from exercice 3).
# * Instances of Child need to have a 'toy' attribute (string), which is defined during instantiation
# * This class should also have a 'playing_with_toy' method, which should return the 'toy' (string) that the Child has.
# * Other than that, a Child should behave exactly like a Human instance, so make sure it is inheriting all the logic from its parents '__init__' method
