- Behaviour of increment and decrement operators in Python
Python does not have unary increment decrement operators (-- ++) Instead, to increment a value, use a += 1 More detail and gotchas But be careful here If you're coming from C, even this is different in python Python doesn't have "variables" in the sense that C does, instead python uses names and objects, and in python ints are immutable
