I'm very new to Python so please excuse any terrible code. The code sometimes prints a list of all the listbox elements like so:
But sometimes the list that is returned is empty. There are two other listboxes on the same webpage and this very same code works consistently for these elements.
Can anyone shed some light on why this is happening? Thanks in advance. Below is the HTML code for the listbox element I am trying to work with.
<p-listbox class="col-md-9 ng-untouched ng-pristine ng-valid" name="ncaList" optionlabel="CodeDisplayValue" _ngcontent-bwu-c7="">
