# 10. Think about how you would change the template so it could allow adding a BoundedInt to an emoji,
|
||||
# if there was a hypothetical function sentiment(emoji) which returned a floating point number from -10.0 to 10.0
|
||||
# which indicated whether the emoji was happy or sad. e.g. BoundedInt(1, min = 1, max = 10) + 😁 would raise ValueError.
|
||||
|
||||
# By adding the conceptional function 'sentiment(emoji)' in the '__add__()' method
|
||||
# The sentiment will analyze the happy level of the input emoji and return a floating number from a number range
|
||||
# For example:
|
||||
# 10 for a 😊 smiley face
|
||||
# -10 for a frowny face
|
||||
# 0 for a 🍕
|
||||
# The protential code can be like this:

'''
