I'm developing a python script in which I use several "print" statements to view the intermediate results in python console of QGIS. Each time after executing the program, I have to manually clear the python console using "Clear Console" option.

Is there a way out to clear the printed statements in python console using a command?

I tried using the following command from this answer

qgis.console.clearConsole()

But I am getting this error message

AttributeError: 'module' object has no attribute 'console'

QGIS offers you several classes for logging messages into the Log Messages Panel (i.e., no need to print debug messages from your plugin into the QGIS Python console). You could even easily create a tab in such panel exclusively for your plugin using QgsMessageLog class:

QgsMessageLog.logMessage( "Info message from plugin", "My Plugin", 0 )
QgsMessageLog.logMessage( "Warning message from plugin", "My Plugin", 1 )
QgsMessageLog.logMessage( "Critical message from plugin!!!", "My Plugin", 2 )
QgsMessageLog.logMessage( "Info message from plugin", "My Plugin", 0 )

Having said that, you can clear the QGIS Python console with these 3 lines:

from PyQt4.QtGui import QDockWidget
consoleWidget = iface.mainWindow().findChild( QDockWidget, 'PythonConsole' )
consoleWidget.console.shellOut.clearConsole()

    That works !! Thanks for the info regarding Log messages panel – Sjs Nov 3 '16 at 13:37
  • BTW, is there a command available to clear the previously logged messages upon new execution? @Germán Carrillo – Sjs Nov 9 '16 at 12:58
  • Rapidly skimming through the API, I couldn't find such command. – Germán Carrillo Nov 9 '16 at 13:38
