$7\mathrm{.}8$ LAB: Word frequencies $($lists$)$

Write a program that first reads in the name of an input file and then reads the file using the csv$.$reader$()$ method. The file contains a list of words separated by commas. Your program should output the words and their frequencies $($the number of times each word appears in the file$)$ without any duplicates.

Ex: If the input is:

input$1.$csv

and the contents of input $\backslash (1.\backslash$mathrm$\{$csv$\}\backslash )$ are:

hello, cat,man, hey, dog,boy,Hello,man,cat,woman,dog, Cat, hey,boy

the output is:

$```$

hello $1$

cat $2$

man $2$

hey $2$

dog $2$

boy $2$

Hello $1$

woman $1$

Cat $1$

$```$

Note: There is a newline at the end of the output, and input$1.$csv is available to download.
