Take a look at Behaviour of increment and decrement operators in Python for an explanation of why this doesn t work    Python doesn t really have    and --  and I personally never felt it was such a loss    I prefer functions with clear names to operators with non-always clear semantics  hence the classic interview question about   x vs  x   and the difficulties of overloading it   I ve also never been a huge fan of what post-incrementation does for readability    You could always define some wrapper class  like accumulator  with clear increment semantics  and then do something like x increment   or x incrementAndReturnPrev
