Sort a List of Dictionaries

Ignition
1

Can anyone provide guidance for how to sort a List of Dictionaries in an Ignition scrip? I’m using the scripting function system.tag.browseConfiguration and I want to sort the results on the ‘name’ key. I did a little research and found that something like the following should work but it doesn’t:

tagConfig = system.tag.browseConfiguration(UDTtagPath, True)
tagConfigSorted = sorted(tagConfig, key=lambda k: k[‘name’])

I get the error message: ‘com.inductiveautomation.ignition.common.tags.config.TagConfiguration’ object is unsubscriptable

Thank you.

Try

 tagConfigSorted = sorted(tagConfig, key=lambda k: k.get('name'))

The ‘unsubscriptable’ error is referring the the square bracket syntax.

Because a TagConfiguration isn't a dictionary.

You beat me to it :stuck_out_tongue:

Thank you both for the help. I see now that the system.tag.browseConfiguration function returns a list of TagConfiguration objects. The suggested code, however, does not work. The error message is:

TypeError: get(): 1st arg can’t be coerced to com.inductiveautomation.ignition.common.config.Property

How do I replace ‘name’ with a property object called “name”?

Thank you.

In this case I think you can actually use k.getName() because TagConfiguration happens to have a getName() method on it.

Kevin,

That worked.

Thank you,
