The original code was too aggressive in ensuring that the channel positions are correct and within bounds. Unfortunately, for Discord this number is merely a guess and there can be gaps that cause the position number to be greater than the number of channels currently in that sorting bucket. One such example of this is when a channel is deleted and created. When this happens, the positions are not updated (presumably because Discord considers this to be too expensive). Sadly this means that if a user were to create a channel, delete a channel, and then create another one then there will be gaps in the position sequence. More concretely, consider the following example: Channels with position [0, 1, 2, 3, 4]. A new channel is created so it inherits the maximum position giving us [0, 1, 2, 3, 4, 5]. We delete a channel that's smaller than the maximum so our list now looks like [0, 1, 2, 4, 5]. Next time we create a channel we will further increment the gap, giving us [0, 1, 2, 4, 5, 6]. If a user would want to move the channel with position 4 to be after position 6 (so in this case that value would 7) then the library would erroneously raise an error because it assumed too much about the data integrity. Luckily, the library upon actually doing the request fixes the channel positions so everything goes back to normal like it was intended. That is to say, [0, 1, 2, 3, 4, 5].

:alt: PyPI supported Python versions
A modern, easy to use, feature-rich, and async ready API wrapper for Discord written in Python.
Key Features
-------------
- Modern Pythonic API using ``async`` and ``await``.
- Proper rate limit handling.
- 100% coverage of the supported Discord API.
- Optimised in both speed and memory.
Installing
----------
**Python 3.5.3 or higher is required**
To install the library without full voice support, you can just run the following command:
.. code:: sh
# Linux/macOS
python3 -m pip install -U discord.py
# Windows
py -3 -m pip install -U discord.py
Otherwise to get voice support you should run the following command:
.. code:: sh
# Linux/macOS
python3 -m pip install -U discord.py[voice]
# Windows
py -3 -m pip install -U discord.py[voice]
To install the development version, do the following:
.. code:: sh
$ git clone https://github.com/Rapptz/discord.py
$ cd discord.py
$ python3 -m pip install -U .[voice]
Optional Packages
~~~~~~~~~~~~~~~~~~
* PyNaCl (for voice support)
Please note that on Linux installing voice you must install the following packages via your favourite package manager (e.g. ``apt``, ``yum``, etc) before running the above commands:
* libffi-dev (or ``libffi-devel`` on some systems)
* python-dev (e.g. ``python3.6-dev`` for Python 3.6)
Quick Example
--------------
.. code:: py
import discord
class MyClient(discord.Client):
async def on_ready(self):
print('Logged on as', self.user)
async def on_message(self, message):
# don't respond to ourselves
if message.author == self.user:
return
if message.content == 'ping':
await message.channel.send('pong')
client = MyClient()
client.run('token')
Bot Example
~~~~~~~~~~~~~
.. code:: py
import discord
from discord.ext import commands
bot = commands.Bot(command_prefix='>')
@bot.command()
async def ping(ctx):
await ctx.send('pong')
bot.run('token')
