Listing all files in a unix directory/sub-directory

Question

I have created the following python script to list all files and their sizes present in directoris/sub-directories

Code A

files = glob.glob("%s/*.*"%os.getcwd())

sorted_file = sorted(files, key=os.path.getsize)

for path, dirs, files in os.walk(os.getcwd()):
    for d in dirs:
        for f in glob.iglob(os.path.join(path, d, '*.*')):
            print f ,os.path.getsize(f)

I am getting the following error when it runs trhough the directories:

Traceback (most recent call last):
  File "Test.py", line 27, in <module>
    print f ,os.path.getsize(f)
  File "/usr/lib/python2.6/genericpath.py", line 49, in getsize
    return os.stat(filename).st_size
OSError: [Errno 2] No such file or directory: '/My/Folder/Perlx.x'

Strangely when I go to the /My/Folder/ in unix box and do a ls -l , I can see Perlx.x whihc it truns out is a Symbolic Link

Code B

for path, subdirs, files in os.walk(os.getcwd()):
    for name in files:
        f = os.path.join(path, name)
        print f,os.path.getsize(f)

Error :

/My/Folder/BEA
Traceback (most recent call last):
  File "Test.py", line 19, in <module>
    print f,os.path.getsize(f)
  File "/usr/lib/python2.6/genericpath.py", line 49, in getsize
    return os.stat(filename).st_size
OSError: [Errno 2] No such file or directory: '/My/Folder/BEA'

In both cases BEA and Perlx.x are Symbolic Links which exits in the specified folder. How do I get rid of this error?

Answer 1

To get rid of the error , I put in an extra condition which checks if the file is link or not.

   for path, subdirs, files in os.walk(choicedir):
        for name in files:
            f = os.path.join(path, name)
            if not os.path.islink(f):
                modified = os.path.getmtime(f)
                size = float(os.path.getsize(f))
