The following problem is not required. However, it is worth $15$ points of extra credit.

$1.$ A quine is a computer program which takes no input$($This implies no file input is allowed$),$ yet prints out its source code. The existence of these

programs is a consequence of the Recursion Theorem.

Create a Python program which is a quine. You may use escape characters such as $\backslash "$ and $\backslash \backslash$ but not special

implementation features such as character codes or pre$-$defined functions such as repr$(),$ exec$(),$ or $\%$r$.$

Submit your answer in two parts:

$($a$)$ A $.$py file.

Your submission will be graded via a method similar to:

$ python$3$ s u b m i s s i o n $.$ py $>$ output

$ d i f f $$q s u b m i s s i o n $.$ py output && echo $$ Quine $!||$ echo $$ Not a q u i n e $.$

$($b$)$ A typed paragraph or two describing how you created the program.

Hint: Assign a string S to serve as a template. The substring operation S$[$i:j$]$ and escaped quotes are useful.
