python - ValueError: too many values to unpack - Is it possible to ignore one value?

Question

The following line returns an error:

self.m, self.userCodeToUserNameList, self.itemsList, self.userToKeyHash, self.fileToKeyHash = readUserFileMatrixFromFile(x,True)

The function actually returns 6 values. But in this case, the last one is useless (its None). So i want to store only 5.

Is it possible to ignore the last value?

Answer 1

You can use *rest from Python 3.

>>> x, y, z, *rest = 1, 2, 3, 4, 5, 6, 7
>>> x
1
>>> y
2
>>> rest
[4, 5, 6, 7]

This way you can always be sure to not encounter unpacking issues.
