<ASSISTANT_TASK:>
Python Code:
import tensorflow as tf
a = tf.constant([1,2,3])
b = tf.constant([4,5,6,7])
def g(a,b):
    tile_a = tf.tile(tf.expand_dims(a, 1), [1, tf.shape(b)[0]])
    tile_a = tf.expand_dims(tile_a, 2)
    tile_b = tf.tile(tf.expand_dims(b, 0), [tf.shape(a)[0], 1])
    tile_b = tf.expand_dims(tile_b, 2)
    cart = tf.concat([tile_a, tile_b], axis=2)
    return cart
result = g(a.__copy__(),b.__copy__())
