You are parsing a configuration file where each line is in the format 'key = value'. The value may contain spaces, and there may be extra spaces around the '='. You need to extract the key and value, trimming any leading/trailing whitespace. Which code snippet correctly parses the line?

key, value = line.strip().split('=')

key, value = line.split('='); key = key.strip(); value = value.strip()

key, value = line.split('=', 1); key = key.strip(); value = value.strip()

key = line[:line.find('=')].strip(); value = line[line.find('=')+1:].strip()

You have a list of strings that may contain leading/trailing punctuation (e.g., '!hello!', '?world?'). You need to remove only the leading/trailing exclamation marks and question marks, but preserve any other punctuation. Which method call is most appropriate?

s.replace('!', '').replace('?', '')

A log line is: 'ERROR: Disk full - retry in 5 minutes'. You need to extract the message after the first colon and then split it into words, but only the first two words are needed. Which code snippet accomplishes this?

msg = log.split(':', 1)[1].strip().split(maxsplit=2)

msg = log.split(':', 1)[1].split(maxsplit=2)

msg = log.split(':', 1)[1].split()[:2]

msg = log.split(':', 2)[1].split(maxsplit=2)

You are cleaning a dataset of usernames that may have extra asterisks (*) at the beginning or end, such as '*alice*'. You need to remove only the asterisks, not any spaces that might be inside the username. Which method call achieves this?

username.lstrip('*').rstrip('*')
