tf.string_join(inputs, separator=None, name=None)

tf.string_join(inputs, separator=None, name=None)

See the guide: Strings > Joining

Joins the strings in the given list of string tensors into one tensor;

with the given separator (default is an empty separator).


  • inputs: A list of at least 1 Tensor objects of type string. A list of string tensors. The tensors must all have the same shape, or be scalars. Scalars may be mixed in; these will be broadcast to the shape of non-scalar inputs.
  • separator: An optional string. Defaults to "". string, an optional join separator.
  • name: A name for the operation (optional).


A Tensor of type string.
