A funny way I just thought of is to delete the variable:
def f(foo, unused1, unused2, unused3): del unused1, unused2, unused3 return foo
This has numerous advantages:
- The unused variable can still be used when calling the function both as a positional argument and as a keyword argument.
- If you start to use it later, you can’t since it’s deleted, so there is less risk of mistakes.
- It’s standard python syntax.
- PyCharm does the right thing! (As of 2020, PyCharm no longer does the right thing 🙁 tracking this at https://youtrack.jetbrains.com/issue/PY-39889 )
- PyLint won’t complain and using
delis the solution recommended in the PyLint manual.
