How does ++ and -- operators work in Python?
In C, C++, Java etc ++ and -- operators increment and decrement value of a variable by 1. In Python these operators won't work.
In Python variables are just labels to objects in memory. In Python numeric objects are immutable. Hence by a++ (if a=10) we are trying to increment value of 10 object to 11 which is not allowed.
>>> a=10 >>> a++ SyntaxError: invalid syntax
Instead we have to use += operator
>>> a=a+1 >>> a 11
