我试着在这个for循环中跳过错误和警告，但是它不起作用?

I am trying to read csv files with their names as dates into a for loop and then print out a few columns of data from that file when it is actually there. I need to skip over the dates that I don't have any data for and the dates that don't actually exist. When I put in my code there is no output, it is just blank. Why doesn't my code work?I am trying to read csv files with their names
