| Parameter               | Description                                                                                                                                                                    |

| `uses_shared_libraries` | default is `False`  The value for the new object's `uses_shared_libraries` field.                                                                                              |

| `has_py2_only_sources`  | default is `False`  The value for the new object's `has_py2_only_sources` field.                                                                                               |

## has\_py2\_only\_sources

```
bool PyInfo.has_py2_only_sources
```

Whether any of this target's transitive sources requires a Python 2 runtime.

## has\_py3\_only\_sources

```
bool PyInfo.has_py3_only_sources
```

Whether any of this target's transitive sources requires a Python 3 runtime.

## imports

```
depset PyInfo.imports
```

A depset of import path strings to be added to the `PYTHONPATH` of executable Python targets. These are accumulated from the transitive `deps`.

The order of the depset is not guaranteed and may be changed in the future. It is recommended to use `default` order (the default).

## transitive\_sources

```
depset PyInfo.transitive_sources
```

A (`postorder`-compatible) depset of `.py` files appearing in the target's `srcs` and the `srcs` of the target's transitive `deps`.

## uses\_shared\_libraries

```
bool PyInfo.uses_shared_libraries
```

Whether any of this target's transitive `deps` has a shared library file (such as a `.so` file).

This field is currently unused in Bazel and may go away in the future.
