It looks like the previous line is clipped at the end.  It needs a closing
" and a closing ] at least.

What is the above line for.  It never reappears below

You never use this either

Or this.

No semicolon in python!

Again, not clear what you need.  You certainly don't need globals.  You may
want to collect all of the Sens_Raw stuff in a list.  If you want that list
to useful to other code, you will need to put it in a module.  Read about
namespaces.
There is nothing wrong with naming things with underscores between the
words.  In fact its recommended.

Sorry, my brain is spinning.  This code is useless.  Why don't you try to
explain what you are trying to accomplish, and you will get better
answers.  As it stands, you perhaps copied this from somewhere.  What is
the data that gets written to text?  Have you any programming skill,
perhaps with another language?
