I just came across an assignment of the form
x, = y
where y is a string (in case it matters).
1. What's the meaning of the comma in the LHS of the assignment?
2. How could I have found this out on my own?
(Regarding (2) above, I consulted the index of several Python
reference books but I could not find the answer to (1). I hope to
find a better Python reference!)
It's unpacking a 1-tuple:
(x,) = y
The parentheses here are not necessary and are sometimes left out.
