Hi,

I’m using 3D-Slicer v4.10.1 and I’m wondering how can I clear **Python Interactor**?

Thanks

For me it works to use the right-click context menu and select all then delete.

is there a python function to do the “clearing” here?  
Thanks

just found solution from @jcfr

You could use the function `ctkPythonConsole::clear()`

From python, the following can be done:

```auto
slicer.app.pythonConsole().clear()

```

From a C++ loadable module, you would have to do something like this:

```auto
#include "qSlicerApplication.h"

// CTK includes
#include <ctkPythonConsole.h>

[...]

qSlicerApplication* app = qSlicerApplication::application();
app->pythonConsole()->clear();

```

You could use:

```auto
>>> slicer.util.pythonShell().reset()

```
