async twitchAPI.helper.first(gen)

Returns the first value of the given AsyncGenerator

Example:

user = await first(twitch.get_users())

Parameters:

gen (AsyncGenerator[TypeVar(T), None]) – The generator from which you want the first value

Return type:

Optional[TypeVar(T)]

async twitchAPI.helper.limit(gen, num)
