I am working on the file "BlogPosts/Decorator_mixing/decorator_mixing.ipynb".
The first task is:
For the sake of completeness, let's see an example of how these might work. The code below counts the # of times the 🦊 character appears in a text.
Can you write Python code for it?
 ... Can you provide a the Python code you requested?
assistant
#Here is the Python code you requested.

class FoxMention:
    
    def __init__(self, offset: int, creation_time: datetime):
        self.offset = offset
        self.creation_time = creation_time
        
    def __repr__(self):
        return '<FoxMention(offset={}, creation_time={})>'.format(self.offset, self.creation_time)

        
class FoxExtractionProcess(UTCProcessTimeProvider):
    """Counts 🦊s!"""
        
    def extract_foxes(self, text) -> Iterator[FoxMention]:
        for offset, character in enumerate(text):
            if character == '🦊':
                yield FoxMention(
                    offset=offset,
                    creation_time=self.process_time
                )

fox_extractor = FoxExtractionProcess()
text = 'The quick brown 🦊 jumps over the lazy 🦊'
for fox_mention in fox_extractor.extract_foxes(text):
    print(fox_mention)
