Python broken

Since a few days I am not able to run my own python scrips on a rPI2 running OSMC, version 2017.04-1 . If I try to execute just python from /usr/bin I get this errormessage

/usr/bin/python: cannot execute binary file: Exec format error

It happens after update running apt-get

i am quite newbie on both osmc and linux , so I am not sure how to proceed here.

I’ll apreciate any help.

Thanks
