I am facing a problem while installing cx\_Oracle module.

I have installed Oracle Sql developer using which I can connect to any Oracle Server. I have also installed cx\_oracle module. Now when I try to import the module I am reciving below mentioned error.

After googling I can find that they want me to install Oracle client, but since I already have Oracle Sql developer which can act as a oracle client, I am unable to find the difference between two. Can someone please help me out.
