Parameters in Python script

TerryGustafson — Sun, 12 Dec 2021 01:09:15 GMT

I'm trying to figure out parameters in python. I created a model and it has some parameters in it. When I run it and create a GP service from it, it asks me to enter those parameters and then runs. I have a python script that I added to a toolbox hoping it would ask for those parameters as well. when I add the script to the toolbox and run it, it says this tool has no parameters. I assumed the in the script arguments from my example that the first_point = arcpy.GetParametersAsText(0) would ask me to enter the first point. Can someone point me in the right direction? TIA

You must add the parameters to the Toolbox script. Right-click the Toolbox script and open the Properties dialog to find the Parameters tab.

That is exactly what I was looking for.. My first_point is a table so would the data type be table for the parameter?

Re: Parameters in Python script

JamesCrandall — Thu, 29 Oct 2015 15:12:44 GMT

From your example code it looks like you are just passing in the path to the table, so... maybe the parameter should just be a string type?

I spoke to soon, I thought I could set those parameters once the GP service was created. If I set them in the script before I run it to publish it, it crashes.. I set them to string..

Traceback (most recent call last):

first_point__2_ = arcpy.GetParameterAsText(2)

My end goal it to add this service to a WAB widget and have the user enter the information from the widget and then it passes the data to the service..

Did you set a parameter for first_point__2_?

thanks for your help, I have been struggling learning this.. I did look at the parameters in the model and it gave me an example so going to try this..

I don't know if its going to work as the only reason I made some of those parameters was to get the model to export the variables correctly so it would run. when I run it through the model with only the first_point and the end_point as parameters and generate the GP service and run it this is the dialog that shows..

I’m thinking the segment would have an output parameter? So the direction would be output? In the parameter properties?

I really do not have an understanding of what you are trying to do with your script. I'd suggest you strip out as much as possible, simplifying things down to bare necessities that accomplishes a portion or a simplified version of what you expect. Then build upon what you learn from that.
