Code error where list index is out of range when doing command like "python3 edfs.py -create /user/file" Trying to follow instruction of python edfs.py -create which will create a file in the specified path. Note the file is empty and your implementation only needs to add the file name to your emulated file system. No need to add data for the file. The command should report an error if the file already exists. Also command "python3 edfs.py -ls /" should list all files under directory but is unable to due to some error that list object has no attribute keys.
