获取函数内部的变量更新(Telegram bot、Python3、python Telegram bot库、多处理)

Question

我正试图用https://github.com/python-telegram-bot/python-telegram-botPython中的库3。

我想让机器人从稍后更新的词典中向我发送信息。这是我现在的代码：

from secret import botToken
import logging
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters
from multiprocessing import Process, Manager
def f(dicts):
    dicts['runNumber'] = 1

def runUp(dicts):
    dicts['runNumber'] += 1

############################# Telegram Bot part #################################

logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
                    level=logging.INFO)
logger = logging.getLogger(__name__)

def botStart(update, context):
    """Send a message when the command /start is issued."""
    update.message.reply_text("Hey ! do /help or /test ")

def test(update, context):
    """Send a message when the command /test is issued."""
    runUp(d)
    update.message.reply_text("run number is now : {0}".format(d['runNumber']))
def help(update, context):
    """Send a message when the command /help is issued."""
    update.message.reply_text("HELP !!")
def echo(update, context):
    """Send a message when message without command is issued."""
    update.message.reply_text("echo")

def error(update, context):
    """Log Errors caused by Updates."""
    logger.warning('Update "%s" caused error "%s"', update, context.error)

def main():
    """Start the bot."""
    updater = Updater(botToken, use_context=True)
    # Get the dispatcher to register handlers
    dp = updater.dispatcher
    # on different commands - answer in Telegram
    dp.add_handler(CommandHandler("start", botStart))
    dp.add_handler(CommandHandler("help", help))
    dp.add_handler(CommandHandler("test", test))
    # on noncommand i.e message - answer in telegram
    dp.add_handler(MessageHandler(Filters.text, echo))
    # log all errors
    dp.add_error_handler(error)
    # Start the Bot
    updater.start_polling()
    # Run the bot until you press Ctrl-C or the process receives SIGINT,
    # SIGTERM or SIGABRT. This should be used most of the time, since
    # start_polling() is non-blocking and will stop the bot gracefully.
    updater.idle()
#################################################################################

if __name__ == '__main__':
    manager = Manager()
    d = manager.dict()
    p1 = Process(target=f, args=(d,))
    p1.start()
    p1.join()
    p2 = Process(target=main)
    p2.start()

但每次我运行/test命令时，我都会从python窗口中的日志中得到以下反馈：

... caused error "name 'd' is not defined"

注意：我不能没有多处理，因为它在我的代码中的其他地方使用

在函数test(update, context)中，d实际上没有定义(它存在于代码中，但在test方法中不可见(。您需要显式使用d作为全局变量，或者将其添加为函数test(及其调用方(的参数。
