Not Python, but you could run a shell script that sends the file with 
lftp, and depending on the return code uses xdg-email to send one of the 
two messages. This would probably be simpler than using Python.

Otherwise you haven't said what part of the process you need help with. 
Reading the log file?  Checking the date?  Triggering the Python script? 
  Sending the email message with Python?

For the latter, it's covered in the Python docs -
