GIS Pro - Python and Arcade Labeling

ChrisGoessl — Fri, 16 Nov 2018 15:39:40 GMT

We are attempting to do a simple if/else statement for labeling on a project but keep coming up with an error. The code is as follows:

def FindLabel ([Name], [Type]):
   if [Type]= 'Church':
      return "Church"
   else:
      return "Not Church"

The error that we are getting is as follows:

Invalid Expression

Error 0 on line 0

File "<string>", line 2

if esri_1 = 'Church':

SyntaxError: invalid syntax

We also worked on arcade (New to us). Here is that code:

if DomainName($feature, 'Type' ="Church") {
return $feature.Name
}
else {
return "Not Church"
}

We get the following error:

Invalid Expression

Error on line 1

Open parenthesis expected.

Any help will be greatly appreciated!

Hi Chris,

For the python portion, when you check if something is equal to, you will want to specify two equal signs (==). Ex:

def FindLabel ([Name], [Type]):
   if [Type]== 'Church':
      return "Church"
   else:
      return "Not Church"‍‍‍‍‍‍‍‍‍‍

ohhhhhhh.... I completely FORGOT about that. That's what happens when you switch between four different computer languages.
