A log file contains lines like 'INFO: user logged in '. A script must extract the message after the colon, remove extra spaces from both ends, and then split it into words. Which code correctly handles this?

msg = line.strip().split(':')[1].split()

msg = line.split(':')[1].split()

msg = line.split(':', 1)[1].strip().split()

msg = line.split()[1].split(':')

A security script must verify that a user-supplied token contains only alphanumeric characters, has a length of at least 8, and does not contain the word 'admin' in any case. Which condition correctly implements all requirements?

if token.isalnum() and len(token) >= 8 and token.lower().rfind('admin') == -1:

if token.isalpha() and len(token) >= 8 and token.find('admin') == -1:

if token.isalnum() and len(token) >= 8 and token.index('admin') == -1:

if token.isalnum() and len(token) >= 8 and token.lower().find('admin') == -1:

A data cleaning function must remove all leading and trailing whitespace from a string, but also remove any leading/trailing occurrences of the character '#' after whitespace is removed. Which sequence of operations is correct?

A developer must create a comma-separated string from a list of mixed-type items, but only include items that are strings consisting solely of letters. Which code achieves this?

result = ','.join([x for x in items if x.isalpha()])

result = ','.join([x for x in items if isinstance(x, str) and x.isalpha()])

result = ','.join(sorted([x for x in items if isinstance(x, str)]))

result = ','.join([str(x) for x in items if isinstance(x, str) and x.isalpha()])
