Syntax error thrown when running on Ubuntu 20.04

[walkabout21]

Python 2.7.18

python convert_notes.py -logseq ~/nextcloud/Notes/ --output ~/Documents/obsidian

  File "convert_notes.py", line 37
    def is_markdown_file(fpath: str) -> bool:
                              ^
SyntaxError: invalid syntax

Python 3.8.1

Traceback (most recent call last):
  File "convert_notes.py", line 58, in <module>
    def get_markdown_file_properties(fpath: str) -> tuple[dict, int]:
TypeError: 'type' object is not subscriptable

I'm not sure why this is throwing this syntax error when I run

Hi @walkabout21 , could you try running it using the latest Python version (or, at least 3.10)? I think that specifying the type of member elements through tuple[dict, int] is only supported in Python 3.9 onwards. Sorry!

If this isn't possible then you could try removing all the type hints from the script.

There may be multiple issues with running this using Python 2, I'm afraid I cannot look into them, I would suggest sticking to Python 3.

PS if you're unfamiliar with Ubuntu, you can update Python by running sudo apt update && sudo apt upgrade -y. After that you can run python3 --version to see what version of Python is now present, then try running the script again.

I'm using the highest version available in ubuntu 20.04 apt packages. I will have to look into if upgrading the python version will cause any os/application issues for me. I've been using Ubuntu for about 15 years and update/upgrade daily. Normally I use Python3 but I was just checking with Python 2 in case it was a legacy problem. Will upgrade my Python version if possible and get back to you.

There was a PPA I used to install a tagged 3.9 version. I ran with that it appeared to resolve. Thanks! Closing the issue.
