Description

Change the directory structure such that the pact/ directory containing all Python files is relocated to src/pact/.

Has this been requested on Canny?

No response

Motivation

The src layout helps prevent a number of issues during development. A discussion by Python's packaging group of the pros can be found at https://packaging.python.org/en/latest/discussions/src-layout-vs-flat-layout/.

Fundamentally, it prevents import pact from finding the local pact/ directory, and ensures that the package is installed correctly (typically as an editable installation).

Have you tried building it?

Self-service

• I'd be willing to contribute this feature to Pact Python myself.
