In Python, accessing static class variables within methods can be challenging, especially when encountering errors like NameError: global name 'bar' is not defined. To resolve this issue, let's explore how to properly access class/static variables.
If you have code like this:
class Foo(object): bar = 1 def bah(self): print(bar)
Calling f.bah() will indeed raise the NameError. The reason is that bar is a static class variable and cannot be accessed with a simple bar within the method bah. To access it, there are two options:
Assigning to Foo.bar will create a static variable, while assigning to self.bar will create an instance variable. By understanding these options, you can effectively access and manipulate class/static variables within your Python methods.
