Answer 1

I would do it this way

file = open('C:\Users\Zain Noman\Desktop\DN-data.csv', 'a+')
writer  = csv.writer(file) #csv wrapper
writer.writerow(['title','news','img-url']) #write the header once
writer.writerows(mylist) #write the the entire list assuming its a list of lists
file.close() #close the file connection

Answer 2

I found the answer and its simple before the writerow line use this

with open('C:Desktop\DN-data.csv', 'a+', newline='') as file:
writer = csv.writer(file, delimiter=',')
if file.tell() == 0
  writer.writerow(['title','news','img-url'])
writer.writerows([mylist])
file.close()
