You can use it through self:
class main:
x=20
def __init__(self):
pass
def func(self):
z=self.x+10
print(z)
obj1=main()
obj1.func()
or through self.__class__
class main:
x=20
def __init__(self):
pass
def func(self):
z=self.__class__.x+10
print(z)
obj1=main()
obj1.func()
or through class name:
class main:
x=20
def __init__(self):
pass
def func(self):
z=main.x+10
print(z)
obj1=main()
obj1.func()

obj1.func()
I always perfer the code goes as the following, to init the value in constructor method.
class main:
def __init__(self):
self.x = 20
def func(self):
z=self.x+10
print(z)
obj1=main()
obj1.func()

Change the first line of func to
z = self.x + 10
