Although be careful with that in Python because there are other situations where (x) and (x,) are both legal but mean very different things.
Also, last I remember in JS a trailing comma meant the creation of an extra array element that’s null so I became conditioned to only use trailing commas for separators in languages where it’s consistent and specified very explicitly like in HCL
w = 0, # w == (0,)
(x) = (0,) # x == (0,)
y, = 0, # y == 0
(z,) = (0,) # z == 0
