Jump statements, such as <code>return</code>, <code>break</code> and <code>continue</code> let you change the default flow of program execution, but jump statements that direct the control flow to the original direction are just a waste of keystrokes.

== Exceptions
|
||
|
|
|
||
|
|
* No issue is raised if the jump statement is the only statement of a statement suite:
|

|

|
||
|
|
def my_function(x):
|
||
|
|
if x > 5:
|
||
|
|
do_something()
|
||
|
|
elif x == 0:
|
||
|
|
return # ok even it could be changed to "pass"
|
||
|
|
else:
|
||
|
|
do_something_else()
|
||
|
|
----
|
||
|
|
* No issue is raised for <code>return None</code> because this was certainly done on purpose to be explicit that a function is really returning <code>None</code>.
