[Python] Text to Speech a conversation using gtts in python

I want to make a dialog between two people in different dialects using gtts. My logic is very simple, the dialog is in a list, if it starts with person 1, then it speaks that and puts it in mp3_files as an mp3. Then I would combine it all to make a single mp3. I keep getting an error and I have no idea how to move on.

import os
from gtts import gTTS
from moviepy.editor import *
import moviepy.editor as mp
from pydub import AudioSegment

# Dialog between two people
dialog = "Person 1: Hi, how are you? \nPerson 2: I'm good, thanks for asking. How about you? \nPerson 1: I'm great, thanks!"

# Split the dialog into separate lines
lines = dialog.split("\n")

# Create an empty list to store the mp3 files
mp3_files = []

# Convert each line of dialog to speech and save as mp3
for line in lines:
if "Person 1" in line:
# Use a male voice for Person 1
tts = gTTS(text=line, lang='en', slow=False)
tts.save("temp1.mp3")
mp3_files.append("temp1.mp3")
elif "Person 2" in line:
# Use a french voice for Person 2
tts = gTTS(text=line, lang='fr', slow=False)
tts.save("temp2.mp3")
mp3_files.append("temp2.mp3")

# Create an empty audio segment
combined = AudioSegment.empty()

# Iterate through the list of mp3 files and concatenate them
for file in mp3_files:
combined += AudioSegment.from_file(file, format="mp3")

# Export the combined audio segment to a new mp3 file
combined.export("dialog.mp3", format="mp3")

# remove the temp files
for file in mp3_files:
os.remove(file)
