How can I access "static" class variables within methods?


If I have the following code:

class Foo(object):
    bar = 1

    def bah(self):
        print(bar)
            
f = Foo()
f.bah()

It complains

NameError: global name 'bar' is not defined

How can I access class/static variable bar within method bah?


Solution

  • Instead of bar use self.bar or Foo.bar. Assigning to Foo.bar will create a static variable, and assigning to self.bar will create an instance variable.
