In ArcGIS Pro, the Expression box of the Label Class pane does not honor Python text parameters for double quotes.

解决办法

Use chr(34) in to ensure double-quotes; however, this would not be apparent by the error message given:

Invalid Expression

Traceback (most recent call last):

File "<expression>", line 1, in <module>

NameError: name 'FindLabel' is not defined
