description: Perform element-wise concatenation of a list of string tensors.

tf.strings.join

Perform element-wise concatenation of a list of string tensors.

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)

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.
