Python Coding Challenge - Question with Answer (01141125)

 

Explanation:

1. Class Declaration

class Counter:

This line defines a class named Counter.

2. Class Variable (Shared Across All Calls)

    x = 1

This is a class variable, not tied to any object.

Its value is shared every time the method is called.

Initial value: 1

3. Method Without self

    def nxt():

        Counter.x *= 2

        return Counter.x

Explanation:

def nxt(): → This method does not use self because we are not creating objects.

Counter.x *= 2 → Every time the method is called, the value of x is doubled.

return Counter.x → The updated value is returned.

4. Loop That Calls the Method Several Times

for _ in range(4):

This loop runs 4 times.

5. Printing the Result Each Time

    print(Counter.nxt(), end=" ")

Each loop iteration calls Counter.nxt()

The returned value is printed

end=" " keeps everything on one line with spaces

Final Output

2 4 8 16
