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.
