I expect
a, b += c, d
to be
a += c; b += d
just like
a, b = c, d
to be
a = c; b = d
Remember that
a,b = c,d
is just tuple assignment without using parens (and pare
Ohh, I never thought it this way. Thanks for enlightening.

a,b = (a,b) + (k,k

Can we pack these two statements in one line ?
a += k
b += k
of course a,b +=k will not work but is there any such option available?
Not that I'm aware. And when I tried it just to see what happens it
