Question

i  have already asked this question and the answer did not work for me:

 

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:

input1.csv

and the contents of input1.csv 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 input1.csv is available to download.
