Question

I am having trouble coding this in python. In the attachment is my solution, but the output does not match the expected output. Instead of having the number 2 beside the words, they all have the number 1

Develop 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
