how to assign multiple variables at once by unpacking array?

[mw]

Interesting: in terms of easy of coding, clarity and future 
maintenance, which one is superior?

The one liner in Python, or your "solution" with dozen lines of 
code? BTW, is that a solution at all? Did it achieved what the 
original goal asked in the OP question?

So, who should learn from whom?
