Zonal statistics error in arcpy

I’m trying to get the zonal statistics output (mean), do some operations and add to my main archive the output value. I wrote this code, but it’s not running, the error message is:

Traceback (most recent call last):

    Zonaltif.save('Z:\04 - Temp\Charles\NDVI_tempo\NAL_PL\teste')

What am I doing wrong?
