Jump statements, such as return
, break
and continue
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.
== Noncompliant Code Example
----
def redundant_jump(x):
if x == 1:
print(True)
return # NonCompliant
----
== Compliant Solution
----
def redundant_jump(x):
if x == 1:
print(True)
----
== 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 return None
because this was certainly done on purpose to be explicit that a function is really returning None
