How to add one more pattern to my street-name regex?

I already have a working example of a regex that matches most German street names. However, I recently learned, that the following patterns are possible as well:

• A 1
• K 7
• H 2
• P 1
• I 7
• E 7
• T 3
• Z 9

How can I build this pattern into my existing Python-regex?:

^(?:[^\W\d_]+\.?|\([^\W\d_]+\.?\))(?:[- '’](?:[^\W\d_]+\.?|\([^\W\d_]+\.?\)))*$

You can just add it with an |. It also seems that your pattern can be heavily simplified:

^(?:[A-Z] \d|[^\W\d_]{2,}\.?)(?:[- '’][^\W\d_]+\.?)*$
