[QGIS-Developer] Multiple python scripts in python console?

[Raymond Nijssen]

Hi Etienne,

Already tried what you are describing. Indeed it's inconvenient, and 
sometimes the changes in the class code did not end up in the class 
definition. For example, a newly defined function on the class was 
unknown in script_1. Might be a bug, but I'm not even sure.

So the best way should be to tell QGIS to run another python script in 
the console. Or go the plugin way.

Thanks and kind regards,

Raymond
