如何删除列表中的撇号，如下所示：
x = [['3.937', '1.968', '1.968'], ['3.937', '1.968', '1.968'], ['3.937', '1.968', '1.968'], ['7.874', '3.937', '1.968'], ['7.874', '3.937', '1.968'], ['7.874', '3.937', '1.968'], ['7.874', '3.937', '1.968'], ['7.874', '3.937', '1.968'], ['7.874', '3.937', '1.968']]
总而言之，我想把这个东西转换成这样：
x = [(3.937,1.968,1.968),(3.937,1.968,1.968)]
result = int(my_list[0])
但存在如下错误： result = int(x[0]) Traceback （最近一次调用最后）：
result = int(x[0])
TypeError: int() argument must be a string, a bytes-like object or a real number, not 'list'
