Is it possible to use a variable as a location?

Basically I want to know if you can use a variable for the name of locating a file. I'll give you an example below (it might not be right though which is why I'm asking how to do it) I was just curious if this is how you do it or there is another way. (In this case part1 is a part in workspace with the name part1 I'm just using a variable string value) Don't ask why I need this, I'm just curious and wanna know.

thebestpart = "part1"

game.Workspace.thebestpart.Transparency = 0
