Pass a variable from one class to another
I am trying to pass one variable from a class to another one. I tried doing it and searched the web but I can't really find out what I was looking for. I have 2 classed names; class1, class2. I am trying to create a variable called self.v in class1 and try to pass it to class2. This is what I have tried so far...
class class1(object):
def __init__(self):
self.create()
def create(self):
self.v = 6
class class2(object):
def __init__(self):
pass
def print(self,c1):
print(self.v)
c = class1()
c1 = c.create()
c2 = class2()
c3 = c2.print(c1)
I also tried doing this:
class class1(object):
def __init__(self):
self.create()
def create(self):
self.v = 6
class class2(object):
def __init__(self,class1):
self.print(class1)
def print(self,class1):
print(self.v)
c = class1()
c1 = class2(c)
.. but that didn't really help fix but the problem either. If someone could please help me, I would appreciate a lot. Thank you.

Have you already worked through the Python tutorial? If not, you should do before trying more complicated things.

Hint: in your first attempt,printtakes an argumentc1that you aren't doing anything with. Maybe you should be doing something with it.

If class2 needs an instance of class1, one obvious solution is to pass the class1 instance to the class2 initializer:
class Class1(object):
def __init__(self, v):
self.v = v
class Class2(object):
def __init__(self, c1):
self.c1 = c1
def print(self):
print(self.c1.v)
c1 = Class1(6)
c2 = Class2(c1)
c2.print()
