Code Explanation:
1. Class Definition
class Counter:
A new class named Counter is defined.
It will contain a class variable and a class method.
2. Class Variable
count = 0
count is a class variable, meaning it belongs to the class, not to any individual object.
It is shared by all instances of the class.
Initial value is set to 0.
3. Class Method Definition
@classmethod
def inc(cls):
cls.count += 1
@classmethod makes inc() a class method.
A class method receives the class itself (cls) instead of an object (self).
cls.count += 1 increases the shared class variable count by 1.
No object creation is needed — this method can be called using the class directly.
4. First Class Method Call
Counter.inc()
Calls the class method inc() using the class name.
This increments count from 0 to 1.
5. Second Class Method Call
Counter.inc()
Calls the method again.
count is incremented from 1 to 2.
6. Printing the Class Variable
print(Counter.count)
Prints the final value of the shared class variable count.
Since inc() was called twice, the value is:
Output:
2
