Write the definition of a class Counter containing: An instance variable named counter of type int. A constructor that takes one int argument and assigns its value to counter A method named increment that adds one to counter. It does not take parameters or return a value. A method named decrement that subtracts one from counter. It also does not take parameters or return a value. A method named get_value that returns the value of the instance variable counter.

This is my code thus far:
def class Counter:
private.counter
def Counter(int init):
counter=value
def void increment():
counter+=
def void decrement():
counter-=
def get_value():
return counter
