tf.strings.join(
    inputs, separator='', name=None
)

Given a list of string tensors of same shape, performs element-wise concatenation of the strings of the same index in all tensors.

tf.strings.join(['abc','def']).numpy()
b'abcdef'
tf.strings.join([['abc','123'],
                 ['def','456'],
                 ['ghi','789']]).numpy()
array([b'abcdefghi', b'123456789'], dtype=object)
tf.strings.join([['abc','123'],
                 ['def','456']],
                 separator=" ").numpy()
array([b'abc def', b'123 456'], dtype=object)

The reduction version of this elementwise operation is tf.strings.reduce_join

Args
inputs	A list of tf.Tensor objects of same size and tf.string dtype.
separator	A string added between each string being joined.
name	A name for the operation (optional).

Returns
A tf.string tensor.
