Pylint default rules need some tuning, it's highly configurable for that 
Some ppl like to think 'module variables' are constants thus should be 
upper case. If you disagree with that statement like I do, you can 
simply rewrite the regexp for module variables.

However, given you example, you should not insert code execution at you 
module level, unless it's required only at the module import. I dont 
know what is your module purpose but I bet it has no legitimate 
attribute 'fun'.
