Is it possible to make a Discord bot print out text from a .log file? (Received some errors)

I am trying to make a Discord bot print out certain text from a .log file with a @event.commanddecorator, but it shows errors. The Discord bot will only print out text when a row of text contains IMPORTANT:

also, the log file in this situation is constantly updating and adding text. I'm on Windows 10 with Python 3.10.11.

I've seen documentation on a bot reading certain text, and then logging it to a txt file, but none showing how to copy off from a .log file directly. and then printing it off to Discord. I was expected to see the bot spit out text that had IMPORTANT: in the rows of the log file. but as soon as I type ?run I only get errors, I am quite new to python, so I would love to see basic corrections on Syntax, and also the errors with the structure of the code,

Here are the errors I receive.

Traceback (most recent call last): File "C:\\Users\\\\AppData\\Local\\Programs\\Python\\Python310\\lib\\site-packages\\discord\\ext\\commands\\core.py", line 235, in wrapped ret = await coro(\*args, \*\*kwargs) File "C:\\Users\\*USER\\OneDrive\\Desktop\\DiscordBot\\main.py", line 18, in follow for line in loglines: TypeError: 'coroutine' object is not iterable

The above exception was the

direct cause of the following exception:

Here is my code:

import discord
import time, os
from discord.ext import commands

@client.event
async def coroutine(ctx, *args): 
  print("Bot Is Ready")

@client.command()
async def run(thefile):
 if __name__ == "__main__":
    logfile = open(os.getenv("APPDATA")+"/.directory/logs/announcement.log", "r")
    loglines = follow(logfile)
    for line in loglines:
        if "IMPORTANT:" in line:
         await print (line)
        
client.run("token is here")

Solution

There are multiple errors in your code, which I will address below. However, we don't know what the follow method does, as it's not a built-in method and you didn't provide the code for it.

Your main problem is that follow is a coroutine, but you didn't await it. Coroutines are asynchronous methods, such as ctx.send and guild.edit in discord.py - you have to put an await before calling that method.

loglines = await follow(logfile)

Now, about the other issues:

The on_ready function must be called on_ready for the library to recognize it, you called it coroutine
Bot.commands' first arguments will always be a 'commands.Context', usually named "ctx". You should update the method declaration: async def run(ctx: commands.Context): (we don't know what thefile is used for, if it's used at all)
if __name__ == "__main__": is usually not supposed to be in a command, but rather at the end of a file, and in this case, it should only contain client.run()
You didn't close logfile, it could cause a memory leakage. logfile.close()
Again, we don't know what follow() does, but you could probably replace it with logfile.readlines(), as this already returns a List[str] (a list containing strings), where every list item is a line from the file
print() is not a coroutine, and even though it does work even if you await it, it's weird and you'll get an error
Indentations are inconsistent, meaning on some lines, you used 3 spaces, while on another, you used 1, and then 2, and 4, etc. - indentations must consistently use the same amount of spaces for them to be recognized properly by the Python interpreter. Use the Tab key in any text editing software
PEP standards dictate that, when using mathematical operators such as +, you should put spaces around them to make the code easily sight-readable
PEP standards also dictate that you shouldn't put a space after calling a method: print ("Hello World") would look weird in comparison to print("Hello World")

PEP standards are basically the "unwritten rules of Python", and PEP 8 is the one describing how one should format their code. It's not required for you to format your code in that exact way - you're completely free to put however many spaces you want after a method's name -, but it's generally more readable and prettier to format your code this way.
