Print df.extent

progis99

So when I write this code

df = arcpy.mapping.ListDataFrames(mxd,"Layers")[0] print df.extent

 

In return the numbers showed me

 

238135.744094489 3606562.79790026 494041.255905512 3787829.20209974 NaN NaN NaN NaN

 

What does NaN NaN NaN NaN   mean ?

 

Is it  laughing at me ??  No, I know !

 

what does it mean, BTW !

 

Thanks

Uh, look at the help?

Extent  ({XMin}, {YMin}, {XMax}, {YMax}, {ZMin}, {ZMax}, {MMin}, {MMax})
