I am trying write discord bots using Python, I have come across and threw together this bot.
import discord
import asyncio
import random
client = discord.Cl
I solved it by installing the updated PyMC from github (they corrected the bug that happens in Python 3.7):
pip install git+https://github.com/pymc-devs/pymc.git
Asynchronous requests were introduced to Python in v3.3, if you're running Python prior to v3.3 (including v2.X), you'll have to install a newer version of Python.
Only if you are running Python 3.3: asyncio
is not part of the stdlib, you'll need to install it manually from pypi:
pip install asyncio
The async
and await
keywords are only valid for Python 3.5 or newer. If you're using Python 3.3 or 3.4, you will need to make the following changes to your code:
@asyncio.coroutine
decorator instead of the async
statement:async def func():
pass
# replace to:
@asyncio.coroutine
def func():
pass
yield from
instead of await
:await coroutine()
# replace to:
yield from coroutine()
Here is an example of what your function need to change into (if you're on 3.3-3.4):
import asyncio
@asyncio.coroutine
def background_loop():
yield from client.wait_until_ready()
while not client.is_closed:
channel = client.get_channel("************")
messages = ["Hello!", "How are you doing?", "Testing!!"]
yield from client.send_message(channel, random.choice(messages))
yield from asyncio.sleep(120)
The aforementioned syntax is still supported in newer versions of Python 3, but it is recommended to use await
and async
if there's no need to support for Python 3.3-3.4. You can refer back to this documentation, here's a short snippet:
The
async def
type of coroutine was added in Python 3.5, and is recommended if there is no need to support older Python versions.
discord.py currently supports 3.4.2-3.6.6, (It does not support 3.3-3.4.1, 3.7 as of January 2019).
For developing with discord.py, I suggest using the discord.py rewrite branch:
discord.py-rewrite supports 3.5.3-3.7.
From version 3.7
async
and await
are reserved keywords
like the error in below image.
Copy and open the path (without __init__.py
).
You will get a list of .py files
Rename async.py
to _async.py
or anything you want, as async is now a reserved keyword with us from version 3.7.
Once renamed, modify the new name everywhere.
*NOTE Although it is not a permanent solution but it worked for me in case of the same syntax error while working with firebase. Best solution is to go with previous version of Python. i.e version below 3.7.
