PyCharm Error?

[coder_sw99]

I have a problem with PyCharm. The Desctructor Method gets initialized, without it even been called. If I try it in the Python IDLE the intepreter doesn´t iniatialize the method, but it in PyCharm it does do it

class Vehicle:
    def __init__(self, nme, ve):
        self.name = nme
        self.velocity = ve
    def __del__(self):
        print("Object", self.name, "got deleted")
    def beschleunigen(self, value):
        self.velocity += value
        self.output()
    def output(self):
        print(self.name, self.velocity, "km/h")

# Objekte der Klasse erzeugen

car1 = Vehicle("Ford",40)
car2 = Vehicle("BMW", 45)

# Objekte betrachten
car1.output()
car2.output()

Output:
Ford 40 km/h
BMW 45 km/h
Object Ford got deleted
Object BMW got deleted

Can somebody help me?
