pyc反编译之后
print ‘Welcome to Re World!‘ print ‘Your input1 is your flag~‘ l = len(input1) for i in range(l): num = ((input1[i] + i) % 128 + 128) % 128 code += num for i in range(l - 1): code[i] = code[i] ^ code[i + 1] print code code = [ ‘\x1f‘, ‘\x12‘, ‘\x1d‘, ‘(‘, ‘0‘, ‘4‘, ‘\x01‘, ‘\x06‘, ‘\x14‘, ‘4‘, ‘,‘, ‘\x1b‘, ‘U‘, ‘?‘, ‘o‘, ‘6‘, ‘*‘, ‘:‘, ‘\x01‘, ‘D‘, ‘;‘, ‘%‘, ‘\x13‘]
稍加修改：
