I wonder if there is a way to open the Python console directly at program launch. There is a possibility to set a shortcut for the Python console, but I can't find such an option for the QGIS program launch.
You can start QGIS Python console when opening a project by writing a couple of lines in
def openProject(): import qgis qgis.utils.iface.actionShowPythonDialog().trigger()
Make sure you enable macros on your project, this way:
Settings->Options->General->Enable macros: Always
As you want the QGIS Python console to open when launching QGIS, you can create (if it doesn't exist already) a
startup.py file in
%APPDATA%\QGIS\QGIS3\ and write:
import qgis qgis.utils.iface.actionShowPythonDialog().trigger()
EDIT (to address a follow-up question by @Miro)
As pointed out by Miro, if QGIS Python Console is open,
qgis.utils.iface.actionShowPythonDialog().trigger() will close it, so, if we are writing a QGIS plugin, it might make sense to know if the Python Console is open (visible) or not.
You can know if the Python Console is not visible (and then open it) by running this code:
from qgis.PyQt.QtWidgets import QDockWidget pythonConsole = iface.mainWindow().findChild(QDockWidget, 'PythonConsole') if not pythonConsole or not pythonConsole.isVisible(): from qgis.utils import iface iface.actionShowPythonDialog().trigger()
