'NoneType' object has no atribute for arcpy.PointGeometry

PabloParra · ‎09-20-2023

Hello! I'm wrapping up my coordenates converter but when I go and run it in ArcGis Pro it got the error down below. I've checked PATH (both) and checked the intalation of the app itself. If you know how to fix it please don't hesitate to reply!

Thanks in advance.

PD: I'll also post the code

arcpy.env.workspace = r"C:\Users\Usuario\Desktop\DocsUSACH\SIG_TAREA1"

Before I read any further, you have converted a python data type (aka, long)

Replace references to 'long' beginning on line 21 with

lng_ = float(long_input)

... sort of retired...

PabloParra · ‎09-20-2023

Done! But not solved it sadly, why is it necessary to change the variable name? Thanks for the Reply!

Also, do you recomend any python editor for windows?.

I look forward to your response!

The idea is to avoid reserved keywords the language uses for normal interpretation of the code. Although I don't see "long" as being one of them, it certainly sounds like a keyword so it's better to avoid it.

As for the error, "'NoneType' object has no atribute for arcpy.PointGeometry" is saying that somewhere you're calling arcpy.PointGeometry with a variable that has a value of None (null). Look at the line it errors and inspect the variables you're using. I suspect one of them is null.
