Static Methods

In Python, classes can have static methods. However there is no real concept for static variables, it can be achieved but that is more advanced than the current scope.

class DateFormatter:
    
    # This is to tell that method is a static one
    @staticmethod
    def format(date_str, format_pattern):
        print('Applying format pattern ' + format_pattern + ' to date arg' + date_str)

    @staticmethod
    def default_format(date_str):
        print('Applying default format pattern to date arg ' + date_str)


# Static methods are called on Class 
DateFormatter.format("280042018", "ddMMyyyy")
DateFormatter.default_format("28-04-2018")

d1 = DateFormatter()
# Static methods can be called from instance too
d1.default_format("28-04-2018")

@staticmethod is the way to tell that a method is static. Static methods can be called as Class.method() or on the instance as well. Note there is no self paramter in the static methods definition.
