Eclipse - Pydev, doesn't recognize not imported methods

I have Eclipse Version: 4.2.1 and PyDev version 2.7.1 installed on my 64-bit Ubuntu. I am using Python 2.7 and I have this problem with Eclipse that it doesn't recognize my un-imported methods. For example if I write a code like this:

def main():
  myfiles = os.listdir('src')

if __name__ == '__main__':
  main()
  print'done!'

I get this error:

Traceback (most recent call last):
  File "tset.py", line 5, in <module>
    main()
  File "tset.py", line 2, in main
    myfiles = os.listdir('src')
NameError: global name 'os' is not defined

which is a pretty obvious error because I didn't write "import os" at the beginning of my code. My problem is that Eclipse doesn't highlight these errors for me anymore. Either I have to find them by myself or I will find out about them when I run my code. My Eclipse was working fine before but I don't know what did I change that this happened.

I should also mention that I have "lib" folder in my project and in that folder I have a few of my own modules and I have added the "lib" folder to PYTHONPATH of my project. And the code that I am running is in another folder named "test" and that's not in the PYTHONPATH.

In addition to the answer by @183.amir, if one of your apps is symlinked (not an actual directory), you need to add it to PYTHONPATH separately (with the steps described above).

The problem was that my code was in a folder like this:

/MyProject/src/test/test.py

But the "src" folder was not in the PYTHONPATH. That is why Eclipse was not recognizing them as a source code and was not analyzing them.

To fix this go to:

Eclipse -> Project -> Properties -> PyDev-PYTHONPATH -> Source Folders

and add "/MyProject/src" to source folders. (I only had "/MyProject/src/lib" in my source folders)
