How to turn a list into a column in a csv?

Currently I have a populated list

list =[a, b, c, d]

I want to convert the content of the list to a csvfile and have all of the elements of the list be one column. This is the current code I have:

with open('twitter3.csv', 'w+') as csvfile:

    writer = csv.writer(csvfile, dialect='excel')

    writer.writerow(list)

The outputted csv file contains the elements of the list but as the method implies, it has written all the contents within the first row.

I have tried making a for loop to write each element + n but the writerow method has an issue with that (puts commas after each letter), and there is no writecolumn method for a csvwriter.

@ShadowRanger sorry about the late response. I do not have any other columns at the moment but likely will in the future. I have decided to just rely on pandas

To perform this task I would use pandas package as follows:

import pandas as pd

l=["a","b","c","d"]

df=pd.DataFrame(l,index=False,header=False)

df.to_csv("twitter3.csv")

pandas is also great to read csv and even work with Excel files.

This is about the simplest way I can think of to do it:

import csv



my_list = ['a', 'b', 'c', 'd']



with open('twitter3.csv', 'w', newline='') as csvfile:

    writer = csv.writer(csvfile, dialect='excel')

    writer.writerows(tuple(item) for item in my_list)

Note I changed the name of your list variable to my_list so it wouldn't conflict with the built-in list class.

You can do this by joining the elements of your list into a single string with new line characters 'nr' as the separators, then write the whole string to your file.

For example:

my_list = [a, b, c, d]



with open("twitter3.csv", "w+") as csvfile:

    to_write = "nr".join(my_list)

    csvfile.write(to_write)

(Also 'n' works)
