python - Pylint警告: Possible unbalanced tuple unpacking with sequence

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)

看来func2总是会返回四个结果。错误是什么意思，为什么？

最佳答案

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