如何使用python3检查嵌套列表中的条件？

list_1=[["22/01/201922222222","22/09/2019"],["abcd1234","poiu0987"],["1","2"],["3.0","4.0"],["5.0--------","6.4"],["3.0","4.0"],["3.0","4.0"]]
list_2=[["22/01/201909","22/09/2019"],["abcd1234","poiu-------0987"],["1","2"],["ab","cd"],["5.0","6.4"]]


Output:
list_1=[["22/01/2019","22/09/2019"],["abcd1234","poiu0987"],["1","2"],["3.0","4.0"],["5.0","6.4"],["3.0","4.0"],["3.0","4.0"]]
list_2=[["22/01/2019","22/09/2019"],["abcd1234","poiu0987"],["1","2"],["ab","cd"],["5.0","6.4"]]
