In Python

I keep getting a white space error in my code

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.

My Code:

import csv

# to store words
words= []
# openfile
with open('input1.csv') as f:
for row in csv.reader(f, delimiter=','):
# read data, add to words
words += row

# get unique words
unique_words = sorted(set(words), key=words.index)

for word in unique_words :
# print words followed by space then its count
print(word , words.count(word), end ='\n'
)
# formatted output at end
print('')
