as I just said, I.method() and C.method(I) are equivalent,
so that's just an odd way to write
'ASFA'.lower()
str().join(['1', '1', '1'])
'a'.join('b')
which, given that str() returns an empty string, and a string
behaves like a sequence of individual characters, is equivalent
to
'ASFA'.lower() => 'asfa'
''.join(['1', '1', '1']) => '111'
'a'.join(['b']) => 'b'
