Silence PyLint warning about unused variables for string interpolation

Question

The say module brings string interpolation to Python, like this:

import say  def f(a):     return say.fmt("The value of 'a' is {a}") 

However, PyLint complains that the variable 'a' is never used. This is a problem because my code uses say.fmt extensively. How can I silence this warning?

Answer 1

Yes, you can silence pylint warnings.

Here is one way:

import say  def f(a):     # pylint: disable=unused-argument     return say.fmt("The value of 'a' is {a}") 

Alternatively, you can create a config file and add these lines to it:

[MESSAGES CONTROL] disable=unused-argument

Answer 2

One approach to silencing that message is to name or prefix the argument with dummy or _, as in:

import say  def f(_a):     return say.fmt("The value of 'a' is {_a}")
