reword title, separate the two examples, convert multiline comment into single-line comment (changed code formatting), removed double occurence of similar meaning (helpful))

Tensorflow: Best practices to write functions for both, modes, eager and graph

Best practices to write functions for both, modes, eager and graph in Tensorflow

I regularly run into the problem that I have a Python function that I want to use in both, eager and graph execution mode. I therefore have to adjust the code so that it can handle both situations. Here are two examples:
```python
import tensorflow as tf
def lin_to_db(x: float | tf.Tensor) -> float | tf.Tensor:
""" convert signal to noise ratio (SNR) from linear to dB """
if tf.is_tensor(x):
return tf.math.log(x) * (10. / tf.math.log(10.))
else:
return math.log10(x) * 10.
def cast_to_int_if_eager(x: tf.Variable) -> int | tf.Variable:
return int(x) if tf.executing_eagerly() else x
```
~~Are there best practices for such functions? Or maybe helpful predefined functions from tensorflow which make my life easier?~~

Tensorflow: Best practices to write functions for both, modes, eager and graph

I regularly run into the problem that I have a python function which I want to use in both, eager and graph execution mode. I therefor have to adjust code so that it can handle both situations. Here are two examples:

`
    import tensorflow as tf

    def lin_to_db(x: float | tf.Tensor) -> float | tf.Tensor:
        """ convert signal to noise ratio (SNR) from linear to dB """

        if tf.is_tensor(x):
            return tf.math.log(x) * (10. / tf.math.log(10.))
        else:
            return math.log10(x) * 10.

    def cast_to_int_if_eager(x: tf.Variable) -> int | tf.Variable:
        return int(x) if tf.executing_eagerly() else x
`

Are there best practices for such functions? Or maybe helpful predefined functions from tensorflow which make my life easier?
