Каждый раз, когда я запускаю команду python main.py add a.txt, я получаю результат, показанный здесь. Буду очень признателен, если кто-нибудь укажет, где я ошибся.

# archive management
#
# For this project you must implement the functionality to manage the space allocation of files.
#
# The storage of the file content itself will not be part of the project, only the allocation of its storage
#
# Each file can have up to 4 datablocks per entry.
# Each file can have up to 9 entries. The sequence (1...9) indicates in which order they should be processed.
# The archive information is stored in ascii (no binary).
# The filesize, sequence and blockid will be store as ascii string, with each fileentry.
#
# the name of the archive, is hardcoded to archive.dat and must be in the current directory
#
# Command Line
#
# just must create and initialize the archive file
# python project3.py  create
#

#
# add a file to the archive.
# python project3.py  add a.txt
#

#
# remove a file from the archive.
# python project3.py  remove  a.txt
#

#
# update a file in the archive.
# python project3.py  update  a.txt
#

#
# list the files in the archives and display information on them.
# python project3.py  list
