arcpy toolbox hides/shows other parameters based on individual parameters

introduce

There are verification parameters in the toolbox properties (as shown below). This part is mainly used to see whether the toolbox parameters meet our requirements. It mainly contains three functions, namely initializeParameters() called when opening the toolbox and called after modifying the parameter value. updateParameters(), set message prompts for parameters updateMessages().

operate

The function we mainly modify is updateParameters()

code

    def updateParameters(self):
        # 修改参数值和属性。
        # 在标准验证之前，每次修改参数时都会调用该函数。
        shpdescribe= arcpy.Describe(self.params[0].value)
        if shpdescribe.shapeType == "Point":
            self.params[1].enabled = False
            self.params[2].enabled = False
        else:
            self.params[1].enabled = True
            self.params[2].enabled = True
        return
