AFAIK `pylint` tries to avoid running the code.

A common idiom to protect code from being executed, if the module is just
imported opposed to executed as main module, is to write::

  def foo():
      # some code

  if __name__ == '__main__':
      foo()

`__name__` is set to the module name if the module will be imported but to
'__main__' if the module is directly executed.
