how to get max and min from a raster using arcpy?

I have a land surface temperature raster file and I want the max and min of it.

minLSTresult = arcpy.GetRasterProperties_management(raster_result, "MINIMUM")

minLST = minLSTresult.getOutput(0)

minLST returns u'261.22'. How could I only get the number of it?

Answer

That is simply indicating that the value is a Unicode string. You can use this unicode string in most situations. However, if you need to fully control the type, convert it to float format.

test = unicode('261.22')

>>> test
u'261.22'

>>> type(test)



test2 = float(test)
>>> test2
261.22

>>> type(test2)
