如何制定工作命令（PyCharm 2020.3.2 Python 3.9）

Question

I created this Economy category for my bot which currently has 2 commands. Balance and Transfer. I am trying to add a work command and I came up with this:

@commands.command()
    async def work(self, ctx):
        id = str(ctx.message.author.id)
        amount = {random.choice(x)}
        amounts[id] += amount
        await ctx.send(f"You worked at a dumpster and earned {random.choice(x)}")

but PyCharm came up with this error:

Ignoring exception in command work:
Traceback (most recent call last):
  File "C:\Users\MainAccount\PycharmProjects\Cat_Bot\venv\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "C:\Users\MainAccount\PycharmProjects\Cat_Bot\cogs\cog_economy.py", line 85, in work
    amounts[id] += amount
TypeError: unsupported operand type(s) for +=: 'int' and 'set'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\MainAccount\PycharmProjects\Cat_Bot\venv\lib\site-packages\discord\ext\commands\bot.py", line 902, in invoke
    await ctx.command.invoke(ctx)
  File "C:\Users\MainAccount\PycharmProjects\Cat_Bot\venv\lib\site-packages\discord\ext\commands\core.py", line 864, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "C:\Users\MainAccount\PycharmProjects\Cat_Bot\venv\lib\site-packages\discord\ext\commands\core.py", line 94, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: unsupported operand type(s) for +=: 'int' and 'set'

Could someone help me to fix this? And please explain the problem if you have the answer

Answer 1

Your error comes from here:

amount = {random.choice(x)}

You're defining amount as a set so adding it to an int causes an error.
What you simply have to do is removing the curly brackets:

@commands.command()
async def work(self, ctx):
    id = str(ctx.message.author.id)
    amount = random.choice(x)
    amounts[id] += amount
    await ctx.send(f"You worked at a dumpster and earned {amount}")

I've also replaced random.choice(x) to amount in your message so it won't display a different amount than the money the member really earned.

Answer 2

First of all, you have an indentation problem. (Ignore if that problem was caused due to copy-pasting)

try amounts[id] += int(amount)

Also, x is not defined...
