I am using eclipse for python. 
  How do I import an existing project into eclipse in the current workspace.
Thanks
First of all make sure that you have the same Python interpreter configured as the project has. You can change it under:
Window > Preferences > PyDev > Interpreters > Python Interpreters
As long the project was created using Eclipse you can use import functionality. 
Go to:
File > Import... > General > Existing Projects into Workspace
Choose Select root directory: and browse to your project location. Click Finish and you are done.
