A script must extract the key and value from lines like `key=value` in a config file. Which code correctly extracts both parts using a named group?

re.match(r'(?P \w+)=(?P \w+)', line).groupdict()

re.search(r'(\w+)=(\w+)', line).groups()

re.findall(r'(\w+)=(\w+)', line)

A developer is parsing a CSV line like `name,age,city` and needs to extract the second field (age). They use `re.split`. Which code correctly extracts the age?

re.match(r'\w+,(\w+)', line).group(1)

re.findall(r',(\w+),', line)[0]

An error that occurs when a regex pattern is too long to compile.
