If you want to put multiple statements on one line (which is not recommended because it typically makes the code less readable), you need to separate them with a ;
(semicolon), not a ,
(comma):
>>> a = 0, b = 1
File "<stdin>", line 1
SyntaxError: cannot assign to literal
>>> a = 0; b = 1
>>> a, b
(0, 1)
