str.startswith and str.endswith

The str.startswith and str.endswith methods are used to check if the given string starts with the given prefix and ends with the given suffix respectively:

'abc'.startswith('ab') # True
'abc'.startswith('bc') # False
'abc'.endswith('ab') # False
'abc'.endswith('bc') # True

What many people don't know is that both methods can accept a tuple of strings. In that case, they check if any of the prefixes/suffixes match:

'abc'.startswith(('ab', 'cd')) # True
'cde'.startswith(('ab', 'cd')) # True
'def'.startswith(('ab', 'cd')) # False
'abc'.endswith(('bc', 'cd')) # True
