How to do next line output from CSV column?

[Pedroski55]

Not sure I understand the request, but this will get you column 4 as a comma separated string, if that is what you want.
You could write string to a csv file.
You can probably do this more elegantly using pandas.

# read straight to a dictionary
# the columns are: fname, lname, department, birthday_month
# so column 4 is birthday_month
import csv
path = '/home/pedro/myPython/csv/'
with open(path + 'employees.txt', mode='r') as csv_file:
    csv_reader = csv.DictReader(csv_file)
    name_records = list(csv_reader) # gives a list of dictionaries where the key is the column header

# here column 4 is 'birthday_month'
# get all   'birthday_month' records as a comma-separated string   
string = ''
for d in name_records:
    string = string + d['birthday_month'] + ','
    # get rid of the last comma
    string = string[0:-1]
