I have two files:

File 1: Takes a text file of a certain format and reformats in a way I prefer

# Dataframe_maker.py
from dataclasses import dataclass
from typing import List
import re

# Defined a class


class Message:
    sender: str
    date: str
    time: str
    content: str
    isreply: bool
    isreact: bool

# This function takes a block of text in a specific format and returns a Message object

def parse_message(Message_Block: str) -> Message:
    lines = Message_Block.split('n')
    sender = lines[2][20:]
    date = lines[2][:10]
    time = lines[2][11:19]
    content = lines[4]
    isreply = '➜ Replying to' in content
    isreact = bool(re.search(r'Laughed at “|Loved “|Questioned “|Emphasised “|Liked “|Disliked “', content))
    
    return Message(sender=sender, date=date, time=time, content=content, isreply = isreply, isreact = isreact)

# I have real addresses here of course

file_path_read = 'filepathRead' 
file_path_write = 'filepathWrite' 

with open(file_path_read, "r", encoding='utf-8') as file_read: 
    data = file_read.read()

# Each message was seperated by this string, and the first message was empty so that is removed

message_blocks = data.split('----------------------------------------------------')
message_blocks.pop(0)

messages: List[Message] = [parse_message(block) for block in message_blocks]

with open(file_path_write, 'w', encoding='utf-8') as file_write:
    for Message in messages:
        file_write.write(f"{Message.sender}, {Message.date}, {Message.time}, {Message.content}, {Message.isreply}, {Message.isreact}n")

# A function that is not used in this file, but is here so I can import it into other files. It takes each line of the output file of this code and converts it back into a Message object

def parse_line(line) -> Message:
    parts = line.strip().split(', ')
    sender, date, time, content, isreply, isreact = parts
    return Message(sender=sender, date=date, time=time, content=content, isreply=isreply, isreact=isreact)

File 2: This is just a test to see if i can actually read the file I created and turn it back into a list of Message objects in a few short lines. The string finding code is just a simple test

from Dataframe_maker import parse_line, Message

file_path = 'filepathRead'

with open(file_path, 'r', encoding='utf-8') as file:
    lines = file.readlines()
messages = [parse_line(line) for line in lines]

# Test begins here

given_string = 'First off, it is important to note that '

for Message in messages:
    if not Message.isreact and not Message.isreply:
        text = Message.content
        if given_string in text:
            index = messages.index(Message)
            length = len(text)
            print(f'The {index}th message is {length} characters long')

The problem I get when I run file 2 is:

• It calls a problem in line 7 of file 2 (defining the List of Message objects)
• Within that line it calls a problem within the parse_line function
• In the function (going back to file 1) it calls a problem in the final line of the function which is the return value of that function, where it returns the input as a Message object
• It says TypeError: ‘Message’ object is not callable

I am not a proficient coder by any means, and this is a hobby project where I am analysing a group chat I share with some friends. I understand what that TypeError means, but to my knowledge the dataclasses in python are callable so I am confused. Any help is appreciated

Edit:
Here is the exact error message (file address changed for privacy):

Traceback (most recent call last):
