5 years ago With e.g. DeprecationWarnings for "invalid escape sequence" the "module" part is the file name (with ".py" removed), because it calls PyErr_WarnExplicitObject directly: https://github.com/python/cpython/blob/3cba3d3c55f230a59174a0dfcafb1d4685269e60/Python/ast.c#L4668-L4692
While this properly cannot be fixed to have the module name (yet), it should at least be documented then.
With warnings.warn the module is set via setup_context (https://github.com/python/cpython/blob/3cba3d3c55f230a59174a0dfcafb1d4685269e60/Python/_warnings.c#L932-L933).
This conflicts with https://github.com/python/cpython/pull/9358 (bpo-34624), which enables the documented behavior to not escape the pattern there.
Note: these values reflect the state of the issue at the time it was migrated and might not reflect the current state.
