파이썬에서 문자열 크기를 비교하는 방법

a = "abc"
b = "abc"
c = "aba"
d = "abd"
print cmp(a,b) 
print cmp(a,c) 
print cmp(a,d)
//返回
0
1
-1

operator.lt(a, b)
operator.le(a, b)
operator.eq(a, b)
operator.ne(a, b)
operator.ge(a, b)
operator.gt(a, b)
operator.__lt__(a, b)
operator.__le__(a, b)
operator.__eq__(a, b)
operator.__ne__(a, b)
operator.__ge__(a, b)
operator.__gt__(a, b)

>>> import operator
>>> operator.eq('hello', 'name');
False
>>> operator.eq('hello', 'hello');
True
