If by "script" you mean quick-and-dirty, then why bother running pylint
on it ? Sounds out of topic to me.
But if you still care about how correctly structured you script should
be, then it should be written almost like a module.
- do not write executable code at the module level
- if a function needs an information, it should ask for it as a
parameter, not using a de-scoped variable (aka global variables)
- if a function ask for too many parameters, then it may ask for few
objects instead (e.g. plot(x,y,z) => plot(point), poor example though, 3
paramaters are acceptable)
- it's better if your script can be imported in a separate file and
the list could contain many more items, and the more item you implement
the closer to a module you get.
