Accessing Static Class Variables Within Methods

When encountering a "NameError" while attempting to access a static class variable within a method, it becomes necessary to adjust the syntax. Here's how to do it effectively:

In the context of the given code:

<code class="python">class Foo(object):
    bar = 1

    def bah(self):
        print(bar)

f = Foo()
f.bah()</code>

The error occurs because "bar" is accessed as a global variable within the "bah" method. To resolve this, two options are available:

1. Access via Class Attribute (Static Variable):

<code class="python">def bah(self):
    print(Foo.bar)</code>

This syntax accesses "bar" as a static variable of the class "Foo," without being attached to a specific instance.

2. Access via Instance Attribute:

<code class="python">def bah(self):
    print(self.bar)</code>

This syntax accesses "bar" as an instance variable within the method. Assignments made to "self.bar" will create instance-specific versions of "bar" for each instance of "Foo."

Additional Note:

Alternatively, setting the class attribute as "self.bar" also affects all instances within the class:

<code class="python">def bah(self):
    print(self.bar)
    self.bar = 2</code>

In this case, subsequent calls to "bah" for other instances will print "2" because instance-specific versions of "bar" are created on the fly.
