python regex to capture SP names

regex_match_sp_name.py

# A regex to describe a (1)first group, (2) a space,  (3)a location enclosed by curly braces
# (4)a bar and a space, (5)a second group, (6)a space, (7) a bar and a space, a (8)last group.
# Spaces are groups by themselves to ease further treatment

pattern = "([^|]+)( )(\\{[\\W\\w\\s]+\\})(\\| )([\\W\\w\\s]+)( )(\\| )([\\W\\w\\s]+)"

Getting the name, type and location could be done as follows:

import re
pattern = "([^|]+)( )(\\{[\\W\\w\\s]+\\})(\\| )([\\W\\w\\s]+)( )(\\| )([\\W\\w\\s]+)"

regex = re.compile(pattern)
match = regex.match("Potash - Potash salt {RER}| market for potash salt | Cut-off, S")
print(f"Name: {match.group(1)}")
print(f"Location: {match.group(3)}")
print(f"Type: {match.group(5)}")
print(f"System: {match.group(8)}")

Name: Potash - Potash salt
Location: {RER}
Type: market for potash salt
System: Cut-off, S
