+**Const** in _TensorFlow_ corresponds to **ConstGen** in _loco_.
+
+_Python_:
+```python
+import tensorflow as tf
+constant = tf.constant(value=[1.0], dtype=tf.float32, shape=[3, 4])
+tf.get_default_graph().as_graph_def()
+```
+
+API reference: [tf.constant](https://www.tensorflow.org/versions/r1.13/api_docs/python/tf/constant)
+
+_TensorFlow_:
+```
+node {
+  name: "Const"
+  op: "Const"
+  attr {
+    key: "dtype"
+    value { type: DT_FLOAT }
