substring >>> s = "anything" | a | n | y | t | h | i | n | g | 0 1 2 3 4 5 6 7 8-8 -7 -6 -5 -4 -3 -2 -1 이렇게 보면 이해가 좀 더 될듯 >>> print sanything>>> print s[:]anything>>> print s[0:]anything>>> print s[:-1]anythin>>> print s+s[0:-1+1]anything>>> print s[-1]g>>> print s[0:-1]anythin>>> print s[:3]+s[3:]anything ------------------------------------------------------------------------------------------..
