# `python3-script-but-no-python3-dep`

Packages with Python3 scripts should depend on the package `python3`. Those with scripts that specify a specific version of Python3 must depend, recommend or suggest on that version of Python3 (exactly).

For example, if a script in the package uses `#!/usr/bin/python3`, the package needs a dependency on `python3`. If a script uses `#!/usr/bin/python3.8`, the package needs a dependency on `python3.8`. A dependency on `python (>= 3.8)` is not correct, since later versions of Python may not provide the `/usr/bin/python3.8` binary.

If you are using debhelper, adding `${python3:Depends}` to the Depends field and ensuring dh_python3 is run during the build should take care of adding the correct dependency.

In some cases a weaker relationship, such as Suggests or Recommends, will be more appropriate.
