Why is this an issue?
A chain of if
/else if
statements is evaluated from top to bottom. At most, only one branch will be executed: the first
one with a condition that evaluates to true
.
Therefore, duplicating a condition automatically leads to dead code. Usually, this is due to a copy/paste error. At best, it’s simply dead code and
at worst, it’s a bug that is likely to induce further bugs as the code is maintained, and obviously it could lead to unexpected behavior.
Noncompliant code example
if param == 1:
openWindow()
elif param == 2:
closeWindow()
elif param == 1: # Noncompliant
moveWindowToTheBackground()
Compliant solution
if param == 1:
openWindow()
elif param == 2:
closeWindow()
elif param == 3:
moveWindowToTheBackground()
