You should always start by mentioning python version and o.s.

The global statement makes no sense here, as you're not inside a 
function.  Everything you've written is global. That means global to 
one module or source file. If you need to access data from another 
module you'll use import,  and if you need to share with another 
process you'll need to use a file, a pipe, a queue,  or some other 
mechanism.

You're clobbering the list every time around the loop.  Move this 
line before the loop.

Use Sens_Raw.append () to add to the end of the list.

Sens_Raw1 to 10 global so I can use it in other programs on the 
Raspberry Pi. The print Sensor wordks fine.
