[question]: Is the main benefit of "Rightward assignments" readability and does this provide more benefits?
makejunk().filter().last(4) => fourthings
fourthings = makejunk().filter().last(4) makejunk | grep foo | tail -4 > fourthings
> fourthings makejunk | grep foo | tail -4
fourthings=$(makejunk | grep foo | tail -4) user.delete() if deleteUser
if deleteUser
user.delete()
end
return if a.nil? return if attempts < max_attempts
In this case "return if" becomes like a keyword and you can ignore it and focus on the rest of the expression. It also seems very readable for other simple values like `return false if ...`. But I agree, as soon as the code to the left of the `if` gets non-trivial it is harder to read.
Any time I use it, I wish python had just gone with the normal ternary (? :) operator.
No, python writes the ternary operator with words, it doesn't have rightward conditionals.
The key difference is that the else clause is required in the Python ternary, where it's optional in a conditional.
