在同一参数中使用整数或字符串的Discord命令

Question

我在制造一个不和机器人。此bot具有Economy命令。我的“撤回”命令只对作为参数的字符串有效。我想用参数“ALL”取所有的钱，用整数取确切的数量。代码如下：

@commands.command()
 async def withdraw(self, ctx, cantidad):
     if type(cantidad) == int and cantidad == 0:
        await ctx.send("Put a valid value")
        return                                  
                                                    
     userStr = str(ctx.message.author)           
     current_bank_balance = database.get_user_bank(userStr)                                                           
     
     if current_bank_balance == 0:                     
         await ctx.send("You dont have money")
         return                                        
                                                          
     if cantidad == "all" or cantidad == "ALL":        
         database.withdraw(userStr, current_bank_balance)
         await ctx.send(f"You withdraw {current_bank_balance} money")
     else:                   
         database.withdraw(userStr, cantidad)
         await ctx.send(f"You withdraw {cantidad} money")    

当您调用draw all时，bot会将所有的钱都带到“银行”，但如果您调用draw 60，则这不起作用

     @commands.command()
     async def withdraw(self, ctx, cantidad = None):
         if cantidad == None:
             await ctx.send("You need to enter an amount")
             return
         if type(cantidad) == int and cantidad == 0:
            await ctx.send("Put a valid value")
            return                                  
                                                        
         userStr = str(ctx.author)           
         current_bank_balance = database.get_user_bank(userStr)                                                           
         
         if int(current_bank_balance) == 0:                     
             await ctx.send("You dont have money")
             return                                        
                                                              
         if str(cantidad.lower()) == 'all': """This will work for 'all' 'All' 'ALl' 'AlL' etc"""
             database.withdraw(userStr, current_bank_balance)
             await ctx.send(f"You withdraw {current_bank_balance} money")

         else:                   
             database.withdraw(userStr, int(cantidad))
             await ctx.send(f"You withdraw {cantidad} money") 

我不确定这是否有效，但试试看
