Trying to robustly parse a string that will have key/value pairs separated

string = 'key_1|||value_1||||key_2|||value_2'
regex = '((?:(?!\|\|\|).)+)(?:\|\|\|)((?:(?!\|\|\|).)+)(?:\|\|\|\|)?'
I am not convinced this is the most effective or safest, any opinions would
be greatly appreciated!
Do you need to use regex?
It would be simpler to use the .split method:
for pair in string.split("||||"):
key, value = pair.split("|||")
print("key is {!r}, value is {!r}".format(key, value))
