如果支付所有命令经济机器人的所有参数值错误

Question

我的代码有效，但是当我包含 pay 'all' 命令时，它似乎给我一个错误。 我希望机器人基本上在我告诉它“.pay @example#0001 all”时选择所有 'bal'

我的代码：

@client.command(aliases=['send'])
async def pay(ctx, member : discord.Member, amount = None):
    await open_account(ctx.author)
    await open_account(member)
    
    if amount == None:
        await ctx.send('Please enter the amount')
        return

    bal = await update_bank(ctx.author)
   


    amount = int(amount)
    if amount == 'all':     #This
        amount = bal[0]     #Wont work

    if amount>bal[1]:
        await ctx.send('You do not have that much money!')
        return
    if amount<0:
        await ctx.send('Amount must be positive!')
        return

    await update_bank(ctx.author,amount, 'wallet')
    await update_bank(member,-1*amount,'bank') 

    await ctx.send(f'{ctx.author.mention} Payed {amount} coins! How generous!')

错误：

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: ValueError: invalid literal for int() with base 10: 'all'

Answer 1

改变这个：

    amount = int(amount)
    if amount == 'all':     #This
        amount = bal[0]     #Wont work

为此：

    if amount == 'all':     #This
        amount = bal[0]     #Wont work
    else:
        try:
            amount = int(amount)
        except ValueError:
            await ctx.send(f'Invalid amount({amount}) Must be "all" or an integer')
            return

这里的想法是您要检查是否发送了“all”，如果没有，则尝试将其转换为整数。如果您无法转换为 int() ，您将收到您所指出的 ValueError 。捕获 ValueError，然后回复用户一条消息。

改变这个：


if amount == None:
    await ctx.send('Please enter the amount')
    return

bal = await update_bank(ctx.author)
   


amount = int(amount)
if amount == 'all':     #This
    amount = bal[0]     #Wont work

收件人：

bal = await update_bank(ctx.author)
if amount == 'all':
    amount = bal[0]
else:
    try:
        amount = int(amount)
    except ValueError:
        await ctx.send(f'Invalid amount({amount}) Must be "all" or an integer')
        return

amount = int(amount) #This has to be after we define "amount == 'all'"
 #THE REST OF THE CODE
