question about classes and variable

Question

I want to make a class Foo . Foo has one input and I want to write a code if I dont use any parameter for that, the output will be 0.
p = Foo()
>>> print(p.x)
0

currently with this program:
class Foo:
x=0;
def __init__(self, x):
self.x=x

I can get zero if I call p=Foo but not p= Foo().
Any idea how can i fix this

Answer 1

Did you try this?

def __init__(self):
self.x = 0
