      **💡 Explanation:**  The `@` operator was added in Python 3.5 keeping scientific community in mind. Any object can overload `__matmul__` magic method to define behavior for this operator.
 
+* From Python 3.8 onwards you can use a typical f-string syntax like `f'{some_var=}` for quick debugging. Example,

 * 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!):
