Description
I recently ran into the following bug and was surprised it wasn't flagged by B018:
def some_funcion(a, b, c, d):
result = a * b
+c * d
return result
that should have been
def some_funcion(a, b, c, d):
result = (
a * b
+ c * d
)
return result
It looks like B018 doesn't trigger for expressions containing multiple variables.
Here's some examples:
a * b # doesn't trigger B018
+a * b # doesn't trigger B018
+1 * 2 # doesn't trigger B018
-1 * 2 # doesn't trigger B018
1 * 2 + 3 # doesn't trigger B018
a + 1 # doesn't trigger B018
a # triggers B018
(a, b) # triggers B018
1 # triggers B018
+1 # triggers B018
-1 # triggers B018
