I am using eclipse for python. 
  How do I import an existing project into eclipse in the current workspace.
Thanks
I just suffered through this problem for a few hours. My issue may have been different than yours...Pydev did not show up as an import option (as opposed to C projects). My solution is to drag and drop. Just create a new project (name it the same as your old) and then drop your old project into the new project folder as displayed in eclipse...3 hours later and it's drag and drop...
How do I import a pre-existing python project into Eclipse?
