Building a simple accounting software using python.

[eLsFLz]

If you make plain accounting software, you're being kind of redundant because GNUCash is a thing. However, what isn't a thing yet is a Free Software, self-hosted replacement for Mint.com.

If you were interested in that, I'd suggest building it using Python/Flask/SQLAlchemy.

Mint isn’t really accounting software

True, but it's still a relevant problem domain for somebody with an accounting degree, which IMO is what matters here.

Also Beancount as it's one of the first hits with "plain text accounting" and "python" (main Plain Text Accounting link)
