using the following instructions write the code in python:

Outline the program

a$)$ Define the three functions:

get$\_$filename$(),$ process$\_$file$(),$

and main$()$

b$)$ Call main at the bottom $($just put

$$main$()$ on the first indent$)$

$2.$ def get$\_$filename$()$:

a$)$ Use input to ask for filename and

store into variable $($filename$)$

b$)$ Return variable

$3.$ def process$\_$file$()$:

a$)$ open$($filename$,\text{'}$r$\text{'},$ encoding$=$'utf$-8)$

b$)$ Create article$\_$count variable

c$)$ For line in file:

$$ If the line starts with URL $($line$[0$:$3]==$URL$)$

$$ Increment article$\_$count

$$ Print out $$Article: #$$

$$ Print out the line with the URL

d$)$ Close the file

e$)$ Print out $$A total of # articles were found!$$

$4.$ def main$()$:

a$)$ Call get$\_$filename$()$ and store it to a variable

b$)$ Call process$\_$file$($variable$\_$name
