why is this not working?

Question

class vehicle :
def __init__(self, nof, length) :
self.nof = nof # number of wheels
self.length = length

def __str__(self):
return f'{self.nof}, {self.length}'

def __repr__(self) :
return f'{self.nof}, {self.length}'

def wcap(self):
n = self.nof
l = self.length
return n * l * 100

class bus(vehicle) :
def __init__(self, length):
super().__init__(length, length)

class car(bus):
def __init__(self, length):
super().__init__(length)

def maxpass(self) :
a = self.lenght
return a *3

class mc(vehicle) :
def maxspeed(self):
l = self.length
n = self.nof
return (l * n)**3

class bike(mc) :
def intro(self):
return "Bikes are just like mcs but without the heavy engine!"

a = mc(2,2)
a.maxspeed()
b= bike(2,3)
b.intro()

Answer 1

You are calling the methods maxspeed and intro, which are returning something but you never print the result.

You should save your code in the playground and link it to your question, so that others have a more convenient way to test it and help you.
