- Define the class with a descriptive name:
- Write the initialization method to include the object to which this object will be connected:
def __init__(self, raw_counter:Counter): self.raw_counter = raw_counter
We've defined a method function that takes a Counter object as an argument value. This counter object is saved as part of the Counter_Statistics instance.
- Define some useful helper methods. Each of these is decorated with @property to make it behave like a simple attribute:
@property def sum(self): return sum(f*v for v, f in self.raw_counter.items()) @property def count(self): return sum(f for v, f in self.raw_counter.items())
- Define the required methods for the various values. ...
