# module `concrete.fhe.extensions.ones`
Declaration of `ones` and `one` functions, to simplify creation of encrypted ones.
---
## function `ones`
```python
ones(shape: Union[int, Tuple[int, ]]) → Union[ndarray, Tracer]
```
Create an encrypted array of ones.
**Args:**
shape (Tuple[int, ...]): shape of the array
**Returns:**
Union[np.ndarray, Tracer]: Tracer that respresents the operation during tracing ndarray filled with ones otherwise
---
## function `one`
```python
one() → Union[ndarray, Tracer]
```
Create an encrypted scalar with the value of one.
**Returns:**
Union[np.ndarray, Tracer]: Tracer that respresents the operation during tracing ndarray with one otherwise
---
## function `ones_like`
```python
ones_like(array: Union[ndarray, Tracer]) → Union[ndarray, Tracer]
```
Create an encrypted array of ones with the same shape as another array.
**Args:**
array (Union[np.ndarray, Tracer]): original array
**Returns:**
Union[np.ndarray, Tracer]: Tracer that represent the operation during tracing ndarray filled with ones otherwise
