Why do I get an error when importing the module to python? #1

import btc_address_dump File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/btc_address_dump/__init__.py", line 4, in <module> from .btc_address_dump import main_entry File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/btc_address_dump/btc_address_dump.py", line 10, in <module> import mnemonic_util File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/btc_address_dump/mnemonic_util.py", line 15, in <module> import common_util File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/btc_address_dump/common_util.py", line 55, in <module> def pubkey_from_bytes_to_point(pubkey: bytes) -> tuple[int, int]: TypeError: 'type' object is not subscriptable

What's going on here? The module should work with python3.8.5, yes?

The “TypeError: ‘type’ object is not subscriptable” error is raised when you try to access an object using indexing whose data type is “type”. To solve this error, ensure you only try to access iterable objects, like tuples and strings, using indexing.

Currently, I only have tested it as command line tool. How to reproduce this issue?

All I did was import btc_address_dump and I got the error.

The root cause is Python3.8 don't supporting Generic Alias Type (https://docs.python.org/3/library/stdtypes.html#types-genericalias).

I have make it compatible with Python3.8, just upgrade it by pip3 install -U btc-address-dump
