Python 3.10 Migration (3 - Claude Sonnet 4.5)

[punitarani-hs]

Greptile Summary

This PR attempts to migrate the project from Python 3.12+ to support Python 3.10+ by reverting version constraints, updating test matrix, and converting StrEnum to str, Enum for the DayOfWeek enum. However, the migration is incomplete: Currency enum in fli/models/google_flights/base.py still uses StrEnum, which will cause import failures on Python 3.10. Additionally, the development container still uses Python 3.12, which is inconsistent with the minimum supported version. The test workflow will fail when running against Python 3.10-3.11.

Confidence Score: 1/5

• This PR has critical compatibility issues that will cause test failures on Python 3.10 and 3.11 during CI execution.
• The PR attempts to add Python 3.10 support but leaves StrEnum usage in fli/models/google_flights/base.py, which was only introduced in Python 3.11. This is a breaking change that directly contradicts the declared minimum Python version of 3.10 in pyproject.toml. The test workflow now tests against Python 3.10-3.11, where this import will fail. Additionally, the development container still uses Python 3.12, creating an inconsistency between the minimum supported version and the development environment.
• fli/models/google_flights/base.py requires immediate attention to change Currency class from StrEnum to str, Enum pattern. The .devcontainer/Dockerfile should also be updated for consistency.

Important Files Changed

Filename	Overview
fli/cli/enums.py	Changed DayOfWeek from StrEnum to str, Enum to support Python 3.10 (StrEnum was introduced in Python 3.11). This is correct and maintains the same behavior.
pyproject.toml	Updated Python version constraints to support Python 3.10+, added classifiers for 3.10 and 3.11, and set Ruff target-version to py310. However, fli/models/google_flights/base.py still uses StrEnum on line 63, which breaks Python 3.10 compatibility.
.github/workflows/test.yml	Extended test matrix to include Python 3.10 and 3.11. This is necessary but will fail during CI because fli/models/google_flights/base.py uses StrEnum which is incompatible with Python 3.10.

Additional Comments (3)

1. fli/models/google_flights/base.py, line 8 (link)

   syntax: StrEnum was introduced in Python 3.11, but pyproject.toml declares requires-python = ">=3.10". This import will fail on Python 3.10. Since fli/cli/enums.py was updated to use str, Enum for DayOfWeek, the same pattern should be applied here for Currency class.

2. fli/models/google_flights/base.py, line 63 (link)

   syntax: StrEnum is not available in Python 3.10. Update to match the pattern used in fli/cli/enums.py:

3. .devcontainer/Dockerfile, line 1 (link)

   style: The development container uses Python 3.12, but the project now supports Python 3.10+ (as declared in pyproject.toml). For consistency with the minimum supported version and to catch compatibility issues during local development, consider updating to Python 3.10:
