Address Field suffixes saved to new field?

Question

I have an address point feature class. I want to extract only the address suffixes in the Address Field into a new field named Suffix. What is the best approach to do this? (I am new to ArcPy, if someone has the code, would you mind posting it? or if there is a better way than using ArcPy?)

Example: 123 Main St

I want St to be placed in a new Suffix field.

There are 5,000 addresses in the feature class.

python parser, replace fld with !TheNameOfYourField! with the ! marks

fld = "123 Main St"
fld.split(" ")[-1]
