Hi all, 


I'm transitioning from ArcMap to ArcGIS Pro - no experience of Python but would like to learn.

I'm trying to run a very simple string function to remove four digits at the end of text field. In ArcMap VB Script I would do the following:



I can't see how to do the same in Python.


There seem to be relatively few examples here: 

Calculate Field examples—Help | ArcGIS Desktop 


and the link to the build in functions of Python returns a 404 error.


Is there a good resource that sets out the functions and arguments for Python in ArcGIS?  I have googled but can't find what I'm looking for!


Thanks in advance for any help,
