how to encode values to csv string in python 3 (args to csv string)

args_to_csv.py

import csv
from io import StringIO


class ArgsToCsv:
    def __init__(self, seperator=","):
        self.seperator = seperator
        self.buffer = StringIO()
        self.writer = csv.writer(self.buffer)

    def stringify(self, *args):
        self.writer.writerow(args)
        value = self.buffer.getvalue().strip("\r\n")
        self.buffer.seek(0)
        self.buffer.truncate(0)
        return value + "\n"

test.py

from args_to_csv import ArgsToCsv

csv_formatter = ArgsToCsv()
output = ""
header = ["age", "text", "my_array"]
output += csv_formatter.stringify(*header)

output += csv_formatter.stringify(
    10,
    """
    lol i have some pretty
    "freaky"
    strings right here \' yo!
    """,
    [10, 20, 30],
)

output += csv_formatter.stringify(10, "hi there", None)

assert output.splitlines() == [
    "age,text,my_array",
    '10,"',
    "    lol i have some pretty",
    '    ""freaky""',
    "    strings right here ' yo!",
    '    ","[10, 20, 30]"',
    "10,hi there,",
]

@sloev Thanks for the snippet. I think you forgot to use separator.
