Why does pylint want 2 public methods per class?

Question

I understand from this answer why the warning exists. However, why would the default value of it be 2?

It seems to me that classes with a single public method aside from __init__ are perfectly normal! Is there any caveat to just setting

min-public-methods=1

in the pylintrc file?

Answer 1

The number 2 is completely arbitrary. If min-public-methods=1 is a more fitting policy for your project and better matches your code esthetic opinions, then by all means go for it. As was once said, "Pylint doesn't know what's best".
