如何将 append 列为 csv 文件中的行 python？

Question

I intend to append following list into a csv file so that it appears in a single row but my code isn't working. I'm a beginner in python. Any suggestions would be welcome. Thank You.

list_one = ['apple','ball','cat','dog']

I tried following code:

import csv

list = ['apple','cat','dog']

with open('document.csv','a') as fd:
  fd.writerows(list)

Answer 1

import csv

list = ['apple','cat','dog']

with open('document.csv','a') as fd:
  write = csv.writer(fd)   
  write.writerow(list)
