Don't understand why you would want to write x=x+3 as x=+3?

Question

for some reason I can't wrap my head around the logic, will appreciate it if someone will explain to me, thanks!

Answer 1

x+=3 is a shortcut way for x=x+3

Answer 2

Thanks guys!

Answer 3

It's a lot clearer to me

Answer 4

It's simply a shortcut, and it doesn't affect readability, and because people want to be more efficient, people do +=, -=, *=, /=, etc.

There is nothing wrong with doing x = x + 3.

Answer 5

The longer the left hand side is, the more useful this shorthand is, also if you are assigning to an array/list/dict element, the index/key is calculated once instead of twice
