# Create a class that implements a context manager as described in 3.3.9.  
# The context manager should keep track of an array of banana emojis.  
# The class should be able to be used with with: so it adds a banana to the list, and upon exit, removes a banana from the list.

# class BananaManager:
#     def __init__(self, bananas):
#         self.bananas = bananas

#     def __enter__(self):
#         self.bananas.append("🍌")
#         return self.bananas

#     def __exit__(self, exc_type, exc_value, traceback):
#         self.bananas.pop()

# # Usage of the banana manager
# banana_list = ["🍌", "🍌"]
# print("Before with statement:", banana_list)

# with BananaManager(banana_list) as adding_bananas:
#     print("Inside with statement:", adding_bananas)

# print("After with statement:", banana_list)



# Questions: can you use a with block inside of another with block?  (You might have to get creative for this to work.). 
# If you can make that work, how many bananas are in the list?

# class BananaManager:

#     with BananaManager(adding_bananas) as inside_bananas:
#         print("Inside second with statement:", inside_bananas)

# print("After with statement:", banana_list)



# Another question: can you structure the program so that you can get the class to have more than 0 bananas *outside* of a with block?
