As a gunsmith who specializes in designing, modifying, and maintaining firearms for various customers including civilians, military, and law enforcement personnel, imagine you have received a custom rifle, let's call it "MyRifle," with a special feature labeled as 'sight' initially set to 'iron sight.' Now, utilizing the 'modifySight' function from the arsenal toolkit, you need to adjust the 'sight' attribute of MyRifle to 'telescopic sight' and display the updated sight configuration.
### Response:
class MyClass:
    def __init__(self):
        self.attribute = 'initial value'

# Instantiate MyClass
my_instance = MyClass()

# Use __setattr__ to set a new attribute value

# Print the updated value
print(my_instance.attribute)
