/ 09 мая 2020

Я пишу бота Discord с помощью discord.py и пытаюсь реализовать систему для покупки акций на python 3.6, поскольку python3 .7 + имеет asyncio.run(func()). 

import discord
import asyncio
import os
import random
import time
import math

client = discord.Client()

# contains coin information including balance, stock price, number of stocks, etc
with open('coins.conf', 'r') as f:
    for line in f.readlines():
        exec(line)

def save_all():
    with open('coins.conf', 'w') as f:
        f.write('coins = '+repr(coins))

random.seed(os.urandom(32))
searchusers = []
bank_cooldown = {}
bans['global'] = False

@client.event
async def on_ready():
    '''Notification on ready.'''
    print('Logged in! Bot running.')
    await client.change_presence(activity=discord.Game(name='/help'))

@client.event
async def on_member_join(user):
    '''Direct message the rules on member join.'''
    await user.create_dm()
    await user.dm_channel.send(f'Hi **{user.name}**, welcome to the server! Be sure to read the rules to stay out of trouble. Have a great time!')

def getcoins(uid):
    '''Get the amount of coins, if nonexistent set to 0.'''
    try:
        return coins[uid][0]
    except Exception:
        coins[uid] = [0, time.time()+1, time.time()+1, 0, 320, time.time()+600, 0]
        return 0

def mention_to_uid(mention):
    '''Extract the UID from a mention (exclude first two char and last char)'''
    uid = mention[2:-1]
    if uid[0] == '!':
        uid = uid[1:]
    return uid

def setcoins(uid, value):
    '''Set the amount of coins someone has.'''
    try:
        coins[uid][0] = value
    except Exception:
        coins[uid] = [value, time.time()+1, time.time()+1, 0, 320, time.time()+600, 0]

asyncio.get_event_loop().run_until_complete(main())

Выполняется только половина функции.

Строка await client.start() не должна быть блокирующим вызовом и в любом случае ожидается. Даже после ожидания 20 минут (максимум 15 минут) вторая часть строки l oop - change = random.choice и все, что ниже, не запускается.

Я думаю, проблема в вызове client.start блокирует, но из документации (https://discordpy.readthedocs.io/en/latest/api.html#discord .Client.start )

await start(*args, **kwargs) Эта функция является сопрограммой. Сокращенная сопрограмма для login () + connect ().

Вызывает ошибку TypeError - был получен неожиданный аргумент ключевого слова. команда start - это сопрограмма.

Я попытался уменьшить время asyncio.sleep до 10 секунд и даже полностью удалить его. Цена акций и сумма джекпота билетов, которые предполагается изменить, не меняются.
