Is there a way to properly synchronize audio video in python?

I am trying to do audio with video automation in Python. I want to synchronize a audio file with video. currently I am using $ to split it into parts wherever there are pause. Is there any other way to do it??.below is code

    # Split the text into parts based on consecutive dollar signs ('$')    text_parts = text.split('$')    # Initialize a list to store translated and speech-generated audio segments    audio_segments = []    # Iterate through text parts    for part in text_parts:        stripped_part = part.strip()        if stripped_part:            # Translate each part            translated_part = self.translate_text(stripped_part, target_language)            # Generate speech for the translated part            tts = gTTS(translated_part, lang=target_language, slow=False)            tts.save("temp_part.mp3")            audio_segment = AudioSegment.from_file("temp_part.mp3")            audio_segments.append(audio_segment)    # Calculate pause duration based on the number of consecutive dollar signs    print(text_parts)    pause_duration = 500 * len(text_parts)    # Create silence for the calculated pause duration    silence = AudioSegment.silent(duration=pause_duration)    # Combine audio segments with silence to create the final audio    final_audio = audio_segments[0]    for segment in audio_segments[1:]:        final_audio += silence + segment    # Export the final audio with pauses    final_audio.export("output_with_pauses.mp3", format="mp3")    # Generate the video with translated speech    self.generate_video_with_speech(self.translate_text(text, target_language), target_language)
