So you have had enough of python goodness but again here comes one of my faviourite things that i like in python. ability to decorate a function or in simple words create a wrapper around an existing function.
This i show we define a basic function in python.
also you need to understand that in python functions are first class objects.i.e we can assign them to a variable , pass around other functions or even define a function inside another function and functions can return anotheer functions.
Now consider this dummy example of creating a function wrapper that always outputs uppercase of a string returned by some function.
