阅读下面的程序: class Test: data1 = 10 def __str__(self): return "data1 = %d" % (self.data1) test = Test() print(test) print(repr(test)) 上述程序最终执行的结果为()。 A. <面向对象.Test object at 0x101ca12e8>data1 = 10 B. <面向对象.Test object at 0x101ca12e8><面向对象.Test object at 0x101ca12e8> C. data1 = 10data1 = 10 D. data1 = 10<面向对象.Test object at 0x101ca12e8>
