Syntax error about File “”, line 1, what does it mean?

Question

Python

I'm trying to run this script to issue roles:

from discord.ext import commands
from discord.utils import get
import discord

bot = commands.Bot(command_prefix='/')

@bot.command(pass_context=True)
@commands.has_role("123") # This must be exactly the name of the appropriate role
async def addrole(ctx):
    member = ctx.message.author
    role = get(member.server.roles, name="Test")
    await bot.add_roles(member, role)

    client = MyClient()
client.run('Тут стоит мой токен :) ')

Next, I write to the console python GGG.py
Gives an error
```

correctness of the path, then try again.

Answer 1

It was necessary to check the box when installing Python Add python 3.X to PATH.
Now this must be done by hand, the instructions are easy to google.
