What it is and what it does
ccy is a Python module that compiles and exposes a dictionary of currency objects, each containing metadata useful for financial analysis. It wraps currency information in a programmatic interface and offers both a Python API and a command-line tool for querying. The module depends on pycountry for country/currency standards, pydantic for data validation, python-dateutil for date handling, and typing-extensions for type hints.
The package is intended for developers who need structured access to currency data in financial applications. It supports querying currencies via the CLI (ccys show) or programmatically in code. An optional holidays extra provides trading centre information, though the core module covers currency fundamentals. The fact sheet notes that not all world currencies are supported, so coverage should be verified for specialized use cases.
Use it for
- Query currency codes, symbols, and metadata in financial analysis or trading applications.
- Build a CLI tool to inspect available currencies and their properties without writing custom data structures.
- Integrate standardized currency information into a backend service that handles multi-currency transactions.
- Reference trading centre holidays and financial calendars when installing the holidays extra.
