#Moving up/down dir structure
print os.listdir('.') # current level
print os.listdir('..') # one level up
print os.listdir('../..') # two levels up
# more complex example:
# This will walk the file system beginning in the directory the script is run from. It
# deletes the empty directories at each level
for root, dirs, files in os.walk(os.getcwd()):
for name in dirs:
try:
os.rmdir(os.path.join(root, name))
except WindowsError:
print 'Skipping', os.path.join(root, name)
</div>
This will walk the file system beginning in the directory the script is run from. It deletes the empty directories at each level.
</div>
