Pls use python string methods to solve this question, thanks

def find_astrological_compatibility (sign_1: str, sign_2: str) -> int: Given two 3-character strings representing star signs, return an int representing how compatible they are. According to Bob' s rules, the compatibility between signs is calculated based on the SIGN_GROUPS they belong in, as follows: - If the signs are in the same group, return 100 - If both the signs are in an odd-numbered group (i. e. 1 and 3) OR if both are in an even group (i. e. 0 and 2), then return 70 - For all other cases, return 50 >>> find astrological_compatibility('ARI', 'LEO') 100 >>> find_astrological_compatibility (GEM', 'LIB') 100 >>> find_astrological_compatibility (SAG', 'AQU') 70 >>> find_astrological_compatibility ('VIR', 'PIS') 70 >>> find_astrological_compatibility ('LEO', 'TAU) 50 >>> find_astrological_compatibility ('AQU', 'SCO) 50, pass
