Getting unwanted “ ” between words when appending a CSV file to a new CSV file in Python 3

Question

I'm trying to append a CSV file to a new CSV file, and where there were no "" between the words in my first document, i get those when appending it to the new file. Example :

house
building 
apartment
loan 

is how is the CSV file I want to import. I wrote this code :

import csv 

csv_file = open("bigcsv.csv", "a", encoding='utf-8', newline = "")
csv_file_writer = csv.writer(csv_file, delimiter= ",")

document_to_append = open("test.csv", "r")
for row in document_to_append:
    print(row)
    csv_file_writer.writerow([row])

document_to_append.close()
csv_file.close()

And the result in CSV is this :

"house
"
"building
"

and so on…

How can I get rid of those annoying ""? I have absolutely no idea…

Answer 1

I'm not sure if this is the reason, but I think it's because you're turning row into a list in the line csv_file_writer.writerow([row]) I'd use this below:

import csv 

with open("bigcsv.csv", "r") csv_file:
with open("test.csv", "w") as csv_file_writer:
    for row in csv_file:
        csv_file_writer.writerow(row)

Answer 2

You can set the csv.writer to quote nothing with quoting=csv.QUOTE_NONE like below:

import csv
csv_file = open("bigcsv.csv", "a", encoding='utf-8', newline = "")
csv_file_writer = csv.writer(csv_file, delimiter= ",", escapechar=' ',quoting=csv.QUOTE_NONE,lineterminator='')
document_to_append = open("test.csv", "r")
for row in document_to_append:
    print(row)
    csv_file_writer.writerow([row])
document_to_append.close()
csv_file.close()

Answer 3

replace the line:

document_to_append = open("test.csv", "r")

by:

document_to_append = [line.rstrip() for line in open('test.csv', "r")]

Note: this will work but you would have to remove the line: document_to_append.close() as document_to_append is no longer a handle, but a list.

If you want to close the file anyhow, then instead of list comprehension(the above solution), do this:

with open('test.csv') as f:
    document_to_append = [line.rstrip() for line in f]
