python - 皮林特警告 : Possible unbalanced tuple unpacking with sequence

Question

我有一段Python代码:

def func1():                                                                                                                  
    a=set()
    b = ','.join(map(str, list(a)))
    return  b, []

def func2():
    d = 1
    e = 2
    return func1() + (d, e,)

def main():
    a,b,c,d = func2()

if __name__ == '__main__':
    main()

当我通过 pylint (1.4.0) 运行它时，我收到警告:

W: 12, 4: Possible unbalanced tuple unpacking with sequence: left side has 4 label(s), right side has 3 value(s) (unbalanced-tuple-unpacking)

func2 似乎总是会返回四个结果。错误是什么意思，为什么？

Answer 1

如果警告是错误的，可以通过将 # pylint: disable=unbalanced-tuple-unpacking 附加到该行来禁用它。
