Extract by Mask for each feature in a feature class

RichNauman

Hello,

I am trying to create a python script to loop through each feature in a feature class and use each feature as the mask for an extract by mask.

Basically I have 12 polygons and want to calculate the mean value of a raster for each polygon - I could split the feature class into 12 feature classes each with one feature and loop through a list of the feature classes but that doesn't seem like the most elegant solution.

Any suggestions?

I tried a using a search cursor to loop through each row and use each row as the mask input value but get  an "Error in executing tool" error.

How do I covert the row object into an input for the tool?

Thanks,

Thanks for the replies everyone.

Snoop pointed me in the direction I needed to go - The MakeFeatureLayer_management step with the where clause is what I didn't know how to do.
