   + `++a` parses as `+(+a)` which translates to `a`. Similarly, the output of the statement `--a` can be justified.
   + This StackOverflow [thread](https://stackoverflow.com/questions/3654830/why-are-there-no-and-operators-in-python) discusses the rationale behind the absence of increment and decrement operators in Python.

   **💡 Explanation:**
-  This prank comes from [Raymond Hettinger's twit](https://twitter.com/raymondh/status/1131103570856632321?lang=en) and it is actually just malformatted `a -= (-1)`. Which is eqivalent to `a = a - (- 1)`. Similar for the `a += (+ 1)` case.

 * Python uses 2 bytes for local variable storage in functions. In theory, this means that only 65536 variables can be defined in a function. However, python has a handy solution built in that can be used to store more than 2^16 variable names. The following code demonstrates what happens in the stack when more than 65536 local variables are defined (Warning: This code prints around 2^18 lines of text, so be prepared!):
