[issue39816] More descriptive error message than "too many values to unpack"

[malcomvx]

malcomvx <malcomvx at tutanota.com> added the comment:

Python functions can return multiple variables . These variables can be stored in variables directly. This is a unique property of Python , other programming languages such as C++ or Java do not support this by default.

The valueerror: too many values to unpack occurs during a multiple-assignment where you either don't have enough objects to assign to the variables or you have more objects to assign than variables. If for example myfunction() returned an iterable with three items instead of the expected two then you would have more objects than variables necessary to assign to.
