Python class instance evaluates to false?

In the following example:

class Example(dict):
  def __init__(self, name):
    self.name = name

  def get_name(self):
    return self.name

ex = Example('ex')
if ex:
  print(ex.get_name())

The if ex statement is evaluating to False and I am not getting any output. What is causing this instance to evaluate to False?
