REGEX expression for finding ship to address of different countries - python-re

Question

I am trying to extract the shipping address from a commercial invoice.
One commercial invoice has ship to destination as Singapore.
The other invoice has ship to destination as Hong Kong
How do I write a regex to extract the destination address, which ends either with Singapore or Hong Kong ?
I wrote a regex to extract the shipping address from a Commercial Invoice. see below:
shipto = re.findall("Shipped To/FRT Forwarder\n[a-zA-Z0-9\s\#\-\,]*SINGAPORE", text).
My problem is the shipping address could be SINGAPORE or HONG KONG or another location. How can I make the regex more generic?
for example:
my shipping address could be
XXXX Singapore
or
YYYY Hong Kong
How do I implement a "either OR" logic in REGEX in the address extraction ?

I found this link helpful.
Here is how you would search for "HONG KONG" or "SINGAPORE".
shipto = re.findall("Shipped To/FRT Forwarder\n[a-zA-Z0-9\s\#\-\,]*(SINGAPORE|HONG KONG)", text)
If you want to generalize, you can do something like this:
shipto_regular_expression_template = "Shipped To/FRT Forwarder\n[a-zA-Z0-9\s\#\-\,]*(LOCATIONS)"
# You could get your list of locations from anywhere.
# These locations will be treated as regular expressions. themselves
list_of_locations = ["SINGAPORE", "HONG KONG", "ELSEWHERE"]
list_of_locations_joined = "|".join(list_of_locations)
shipto_regular_expression = shipto_regular_expression_template.replace("LOCATIONS", list_of_locations_joined)
re.findall(shipto_regular_expression_template, text)
