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.
