[docs]@decorate def apply(coro, *args, **kw): """ Creates a continuation coroutine function with some arguments already applied. Useful as a shorthand when combined with other control flow functions. Any arguments passed to the returned function are added to the arguments originally passed to apply. This is similar to `paco.partial()`. This function can be used as decorator. arguments: coro (coroutinefunction): coroutine function to wrap. *args (mixed): mixed variadic arguments for partial application. *kwargs (mixed): mixed variadic keyword arguments for partial application. Raises: TypeError: if coro argument is not a coroutine function. Returns: coroutinefunction: wrapped coroutine function. Usage:: async def hello(name, mark='!'): print('Hello, {name}{mark}'.format(name=name, mark=mark)) hello_mike = paco.apply(hello, 'Mike') await hello_mike() # => Hello, Mike! hello_mike = paco.apply(hello, 'Mike', mark='?') await hello_mike() # => Hello, Mike?
