python_sources

Generate a python_source target for each file in the sources field.

You can either use this target generator or python_test_utils for test utility files like conftest.py. They behave identically, but can help to better model and keep separate test support files vs. production files.

Backend: ``

dependencies​

Iterable[str] | None
default: None

Addresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib'].

Alternatively, you may include file names. Pants will find which target owns that file, and create a new target from that which only includes the file in its sources field. For files relative to the current BUILD file, prefix with ./; otherwise, put the full path, e.g. ['./sibling.txt', 'resources/demo.json'].

You may exclude dependencies by prefixing with !, e.g. ['!helloworld/subdir:lib', '!./sibling.txt']. Ignores are intended for false positives with dependency inference; otherwise, simply leave off the dependency from the BUILD file.

description​

str | None
default: None

A human-readable description of the target.

Use ./pants list --documented :: to see all targets with descriptions.

interpreter_constraints​

Iterable[str] | None
default: None

The Python interpreters this code is compatible with.

Each element should be written in pip-style format, e.g. CPython==2.7.* or CPython>=3.6,<4. You can leave off CPython as a shorthand, e.g. >=2.7 will be expanded to CPython>=2.7.

Specify more than one element to OR the constraints, e.g. ['PyPy==3.7.*', 'CPython==3.7.*'] means either PyPy 3.7 or CPython 3.7.

If the field is not set, it will default to the option [python].interpreter_constraints.

See https://www.pantsbuild.org/v2.8/docs/python-interpreter-compatibility for how these interpreter constraints are merged with the constraints of dependencies.

overrides​

Dict[Union[str, Tuple[str, ...]], Dict[str, Any]] | None
default: None

Override the field values for generated python_source targets.

Expects a dictionary of relative file paths and globs to a dictionary for the overrides. You may either use a string for a single path / glob, or a string tuple for multiple paths / globs. Each override is a dictionary of field names to the overridden value.

For example:

overrides={
  "foo.py": {"skip_pylint": True]},
  "bar.py": {"skip_flake8": True]},
  ("foo.py", "bar.py"): {"tags": ["linter_disabled"]},
}

File paths and globs are relative to the BUILD file's directory. Every overridden file is validated to belong to this target's sources field.

If you'd like to override a field's value for every python_source target generated by this target, change the field directly on this target rather than using the overrides field.

You can specify the same file name in multiple keys, so long as you don't override the same field more than one time for the file.

skip_autoflake​

bool
default: False

If true, don't run Autoflake on this target's code.

skip_bandit​

bool
default: False

If true, don't run Bandit on this target's code.

skip_black​

bool
default: False

If true, don't run Black on this target's code.

skip_docformatter​

bool
default: False

If true, don't run Docformatter on this target's code.

skip_flake8​

bool
default: False

If true, don't run Flake8 on this target's code.

skip_isort​

bool
default: False

If true, don't run isort on this target's code.

skip_mypy​

bool
default: False

If true, don't run MyPy on this target's code.

skip_pylint​

bool
default: False

If true, don't run Pylint on this target's code.

skip_pyupgrade​

bool
default: False

If true, don't run pyupgrade on this target's code.

skip_yapf​

bool
default: False

If true, don't run yapf on this target's code.

sources​

Iterable[str] | None
default: ('*.py', '*.pyi', '!test_*.py', '!*_test.py', '!tests.py', '!conftest.py', '!test_*.pyi', '!*_test.pyi', '!tests.pyi')

A list of files and globs that belong to this target.

Paths are relative to the BUILD file's directory. You can ignore files/globs by prefixing them with !.

Example: sources=['example.ext', 'test_*.ext', '!test_ignore.ext'].

tags​

Iterable[str] | None
default: None

Arbitrary strings to describe a target.

For example, you may tag some test targets with 'integration_test' so that you could run ./pants --tag='integration_test' test :: to only run on targets with that tag.
