== Why is this an issue?

Having all branches of an `if` chain with the same implementation indicates a problem.

In the following code:

[source,python]
----
if b == 0:  # Noncompliant
    do_one_more_thing()
elif b == 1:
    do_one_more_thing()
else:
    do_one_more_thing()

b = 4 if a > 12 else 4  # Noncompliant
----

Either there is a copy-paste error that needs fixing or the unnecessary `if` chain needs removing.

=== Exceptions

This rule does not apply to `if` chains without `else`.


[source,python]
----
if b == 0:  # no issue, this could have been done on purpose to make the code more readable
    do_one_more_thing()
elif b == 1:
    do_one_more_thing()
