code: def dim_handling(inputs, dim=None, dims=None, broadcastables=None):
      r"""
      Get value of ``broadcastables`` argument to :func:`.theano_code` from
      keyword arguments to :func:`.theano_function`.
  
      Included for backwards compatibility.
  
      Parameters
      ==========
  
      inputs
          Sequence of input symbols.
  
      dim : int
          Common number of dimensions for all inputs. Overrides other arguments
          if given.
  
      dims : dict
          Mapping from input symbols to number of dimensions. Overrides
          ``broadcastables`` argument if given.
  
      broadcastables : dict
          Explicit value of ``broadcastables`` argument to
          :meth:`.TheanoPrinter.doprint`. If not None function will return this value unchanged.
  
      Returns
      =======
      dict
          Dictionary mapping elements of ``inputs`` to their "broadcastable"
          values (tuple of ``bool``\ s).
