Built-in Function len() The most straightforward and common way to get the number of elements in a list is to use the Python built-in function len(). Let's look at the following example: ADVERTISEMENT list_a = ["Hello", 2, 15, "World", 34] number_of_elements = len(list_a) pri...

I am writing a custom python expression function to return the value of a variable. By variable, I mean the layer, project, or global variables. I looked at this answer https://gis.stackexchange.com/a/189815/94852 and came up with the following code. from qgis.core import * from qgis....
from youtubesearchpython import Transcript print(Transcript.get("https://www.youtube.com/watch?v=-1xu0IP35FI"))In response, you'll get available languages with params parameter. If you want to retrieve a different language, you have to pass the function that parameter. Example:...
