Additional Information
Changes were made around 10.2.2 to properly isolate script tool code, validation and tool like Calculate Field and Calculate Value that use Python internally. Prior to this change, there was potential for confusing and unexpected issues that would be hard to isolate because a variable could be changed in one tool that would impact another tool. The best strategy for passing variables into CalculateField is using string formatting as shown in the workaround.Workaround
Use the following code:arcpy.CalculateField_management(table,"gayu", "({0} + 1) / 2".format(funcg), "PYTHON", "")Steps to Reproduce
