== Why is this an issue?

When two functions or methods have the same implementation, either it was a mistake - something else was intended - or the duplication was intentional, but may be confusing to maintainers. In the latter case, one implementation should invoke the other. Numerical and string literals are not taken into account. 

=== Noncompliant code example

[source,python]
----
class MyClass:
    code = "bounteous"

    def calculate_code(self):
        self.do_the_thing()
        return self.__class__.code

    def get_name(self):  # Noncompliant
        self.do_the_thing()
        return self.__class__.code

    def do_the_thing(self):
        pass  # on purpose
----

=== Compliant solution

[source,python]
----
class MyClass:
    code = "bounteous"

    def calculate_code(self):
        self.do_the_thing()
        return self.__class__.code

    def get_name(self):
        return self.calculate_code()

    def do_the_thing(self):
        pass  # on purpose
----

=== Exceptions

No issue will be raised on empty methods/functions and methods/functions with only one line of code.
