Function to clean up the text by removing inline tags and extra formatting
def clean_text(captions): cleaned_captions = [] for caption in captions: text = re.sub(r”<.*?>”, "", caption[“text”]) # Remove inline tags text = re.sub(r”\s+”, ” ”, text).strip() # Remove extra whitespace cleaned_captions.append({“timestamp”: caption[“timestamp”], “text”: text}) return cleaned_captions
Clean the parsed captions
cleaned_captions = clean_text(captions)
Combine cleaned captions into a readable format for summarization
combined_text = ” “.join([caption[“text”] for caption in cleaned_captions])
Display a snippet of the cleaned text to verify the cleaning process
combined_text[:500] # Display the first 500 characters for review
