I need help with coding in python! class CommandLine:

def __init__(self):

self. root = Directory('', None)

self. current_path = self. root

def run(self):

command = input('>>> ')

while command. strip().lower() != 'exit':

split_command = command. split()

if len(split_command):

if split_command[0] == 'ls':

self. current_path. display()

if len(split_command) >= 2:

if split_command[0] == 'cd':

self. change_directory(split_command[1])< br />
elif split_command[0] == 'makedir':

self. current_path. create_directory(split_command[1])< br />
elif split_command[0] == 'fcreate':

self. current_path. create_file(split_command[1])

elif split_command[0] == 'fwrite':

self. current_path. file_write(split_command[1])

elif split_command[0] == 'fread':

self. current_path. file_read(split_command[1])

elif split_command[0] == 'fclose':

self. current_path. close_file(split_command[1])

elif split_command[0] == 'fopen':

self. current_path. open_file(split_command[1])

command = input('>>> ')

cmd_line. run()
You must keep track of your current directory, and then you must be able to execute the commands listed below.

(The commands are explicitly different from linux so that you don't accidentally execute them in the shell, except for ls and cd which are harmless.)

Command

ls
Lists contents of the directory
cd [dirname]
Change directory up or down one level.
makedir [dirname]
Make a directory
fcreate [filename]
Creates a file, sets it closed.
fwrite [filename]
Write to a file, only if it's open.
fread [filename]
Read a file, even if it's closed.
fclose [filename]
Close a file. Prevents write.
fopen [filename]
Open a file. Reset the contents
