I had surgery on my pinky tendon about 1 week ago i still have about another week till i go back to the doctor, will it be healed by then?

Depends: You need to ask your surgeon. The recovery is multi-variable. As an informed patient you should know exactly what was done, have a copy of the operative report most importantly you should have had that question answered by your surgeon by this point.

Up to your surgeon: There is not enough information to know what kind of surgery you had on your tendon. If it was something simple like a "trigger finger" release, then it may be possible. If you had a tendon repair or transfer, you may be looking at a much longer recovery. I would defer this question to the surgeon who took care of you.

6-8 weeks: This is how long it needs to heal. You'll need specialized therapy as well.
