This is not the actual code you are using, because this gives a
SyntaxError. You are missing a closing parentheses.
Please don't retype your code from memory. Copy and paste the actual
code. It is hard enough to work out what code does when we can see it, it
is next to impossible to work out what it does when we're given
*different* code and have to guess how many changes have been made.

Are you sure that is the OUTPUT?
It looks more like the input -- the command you are running. Have you
looked inside the file
where output is going?
By the way, as a total beginner to this, I don't think you need the extra
complexity and discipline of using log files. Don't try catching errors
and logging them. Let the errors fail. While you are learning, the BEST
thing to do is to learn to read the tracebacks and fix the bug in your
code, not to try to cover them up and bury the failures inside a log file.
If you need informational messages, just use print.
You can come back to logging when you have more experience.
(I've been programming with Python for 20+ years, and I still use print
for simple scripts and when learning a new library.)
