The purpose of the staticmethod function is to
convert a method into a static method. See Section 26.4, “Static methods” for definitions and
usage.
Typically you will declare a static method using the decorator syntax, like this:
@staticmethod
def methodName(...):
method body
An alternative is to place a line like this after the method's definition (at the same
indentation level as its def):
methodName= staticmethod(methodName)
