How can I do this with Python?
Like this:
import Rhino
for i in range(1000):
Rhino.RhinoApp.WriteLine("")
On a more serious note, the correct method to use is this: 
import Rhino
Rhino.RhinoApp.ClearCommandHistoryWindow()
But I don’t want to clean the command history just this list there. You know in cmd if you enter cls you can still get your previous commands using the [kbd]UpArrow[/kbd]
sidenote: what’s with the kbd tag 
? @dan ?
I’m not sure, is there even a type of up and down arrow function in rhino for the commandline?
It was just an example that cls does not clean the history just the screen/terminal in CMD
Well going solely by the name of that function i would assume it behaves exactly like cls
It doesn’t, it also cleans up the history of the commands.
try this:
- start several commands. Place some points in 3d.
- launch this from python:
import Rhino
#Rhino.RhinoApp.ClearCommandHistoryWindow()
print Rhino.RhinoApp.CommandHistoryWindowText
3 . then try your command
4 . and again launch step 2.
Result:
The commands that you used to create the objects are not displayed, they are removed from the history. I want to simply clean this window without deleting the history.
I run some commands…
I call the function:
Rhino still knows the history of commands, just the Text has been cleared, exactly like cls
Try this out:
import Rhino
print Rhino.RhinoApp.CommandHistoryWindowText
Rhino.RhinoApp.ClearCommandHistoryWindow()
print Rhino.RhinoApp.CommandHistoryWindowText
for command in Rhino.Commands.Command.GetMostRecentCommands():
print command.DisplayString

I found an other solution if someone is interested
it worked inside grasshopper too
import Rhino
listcommands = Rhino.RhinoApp.CommandHistoryWindowText
Rhino.RhinoApp.ClearCommandHistoryWindow()
Rhino.RhinoApp.Write(listcommands)
