Checking list by using of exception

[Nader]

Hello,

I read some files name from a directory and then I put these name in a
list. I will check whether it is empty or not, and I would do it with
an exception. With if statement it is very simple:

If list_of_files != ""  :            # this can be if list_of_files !=
[]:
  get the files
elas:
   there is no file

But with exception, I can write something as:

try:
   list_of_files != []
   get the files
except ValueError:
    Print " there is no file"

What can the first statement be inside 'try' if I don't want to use if
statement?
Maybe my understandig of exception is enough to got it.

Would somebody explain me about this?

Regards,
Nader
