avoid_ empty_ else
Avoid empty statements in else clauses.
Details
#
AVOID
empty statements in the
else
clause of
if
statements.
BAD:
if (x > y)
print('1');
else ;
print('2');
If you want a statement that follows the empty clause to
conditionally
run,
remove the dangling semicolon to include it in the
else
clause.
Optionally, also enclose the else's statement in a block.
GOOD:
if (x > y)
print('1');
else
print('2');
GOOD:
if (x > y) {
print('1');
} else {
print('2');
}
