Python- can someone help me with the logic

Question

Class Geom(object):
def __init__(self, h=10, w=10):
self.h , self.w=h,w
def rectangle (self):
rect= self.h*2 + self.w*2
return rect
a= Geom(4)
print(a.rectangle())

Answer 1

geom(4) overrides the first parameter h with 4, w stays at the default 10.
rect = 4*2 + 10*2
rect = 8 + 20
return 28

Answer 2

where can't you understand?

Answer 3

you passed it a value, if you just do a=Geom() it will use both defaults, can also do a = Geom(w=4) to specify which parameter to override, or a = Geom(4,5) to override both

Answer 4

thanks .can u pls help me understand why does it override

Answer 5

got it.thank you
