# sympy and sage

Playing with Sage and Sympy I accidentally ran sage from the directory `~/.config/ipython/profile_sympy`

and noticed that the "engine" of symbolic computation has changed:

```
type (1)
sympy.core.numbers.One
```

The same thing happens if from sage to execute:

```
from sympy import *
```

Is it experimental feature? Will it grow? What are plans to integrate sympy and sage if they are? What about some quirks (in sympy, for example, I can't define something like `f(x) = x+1`

)

Thank you and sorry for my English.
