# tensorplay.is_tensor

Source: https://www.tensorplay.cn/docs/generated/tensorplay.is_tensor.html

```python
tensorplay.is_tensor(obj: Any, /) → TypeIs[Tensor]
```

Returns True if obj is a TensorPlay tensor.

Note that this function is simply doing isinstance(obj, Tensor).
Using that isinstance check is better for type checking with mypy,
and more explicit - so it’s recommended to use that instead of
is_tensor.

Parameters:

obj ([object](https://docs.python.org/3/builtins/functions.html#object)) – Object to test

Example:

```
>>> x = tensorplay.tensor([1, 2, 3])
>>> tensorplay.is_tensor(x)
True
```
