Depending on the way this object was created, some of the attributes can

.. describe:: x == y
Checks if two reactions are equal. This works by checking if the emoji
is the same. So two messages with the same reaction will be considered
"equal".
.. describe:: x != y
Checks if two reactions are not equal.
.. describe:: hash(x)
Returns the reaction's hash.
.. describe:: str(x)
Returns the string form of the reaction's emoji.
Attributes
-----------
emoji: Union[:class:`Emoji`, :class:`PartialEmoji`, :class:`str`]
The reaction emoji. May be a custom emoji, or a unicode emoji.
count: :class:`int`
Number of times this reaction was made
me: :class:`bool`
If the user sent this reaction.
message: :class:`Message`
Message this reaction is for.

Remove the reaction by the provided :class:`User` from the message.

Parameters
-----------
user: :class:`abc.Snowflake`
The user or member from which to remove the reaction.
Raises
-------
HTTPException
Removing the reaction failed.

You do not have the proper permissions to remove the reaction.

Usage ::

Flattening into a list: ::

Parameters
------------
limit: :class:`int`
The maximum number of results to return.
If not provided, returns all the users who
reacted to the message.
after: :class:`abc.Snowflake`
For pagination, reactions are sorted by member.
Raises
--------
HTTPException
Getting the users for the reaction failed.
Yields
--------
Union[:class:`User`, :class:`Member`]
The member (if retrievable) or the user that has reacted
to this message. The case where it can be a :class:`Member` is
in a guild message context. Sometimes it can be a :class:`User`
