if 怎么写else呢？怎么让不会字符串的，也能显示呢？怎么写呢？

#2 Created at ... [Delete] [Delete and Lock User] 
L2 = [s.lower() for s in L1 if isinstance(s,str) else s]

反正这么写是不对了，估计在列表生成式中不支持else语句吧

#3 Created at ... [Delete] [Delete and Lock User] 
L2 = [s.lower() if isinstance(k,str) else s for s in L1]

在楼下看到的，搬运上来，试过是正确的

不好意思，isinstance里面应该是s不是k
