Difference between python toolbox and python external ?

OlivierOlivier — Mon, 27 Feb 2012 18:57:17 GMT

Hi,

I try to list all layers from an mxd. Can someone explain me why it works when launched from toolbox and not from an Idle python script ?

mxd = arcpy.mapping.MapDocument(r"...\my.mxd") for df in arcpy.mapping.ListDataFrames(mxd,"*"):     for lyr in arcpy.mapping.ListLayers(mxd,"*",df):         print df.name + ":" + lyr.name

When launched with a tool inside Arcmap 10.0, I get all layers, but from python 2.6 script, it just displays the first layer and stops (Layers:<first layer name>).

Thanks for any help

Olivier

It worked fine for me from IDLE. Have you tried it using different mxds?

Thanks Matthew, your answer helped me to investigate, it worked with other mxd.

So I did a reboot and finally it's ok. A bit strange but as I did many Python tests on this machine and this mxd during the previous day, perhaps something gone wrong.
