python 两个多维列表如何合并为另外的多维列表？

a = [['1','扶摇','fuyao'],['2','战狼','ZL']]

b = [['点击数','3','分数:5'],['点击数','5','分数:10']]

最终想要结果为 [['1','扶摇','fuyao'],['2','战狼','ZL'],['点击数','3','分数:5'],['点击数','5','分数:10']]

就直接写c = a + b 就行了

a = [['1', '扶摇', 'fuyao'], ['2', '战狼', 'ZL']]
b = [['点击数', '3', '分数:5'], ['点击数', '5', '分数:10']]

c = a + b
print(c)
