如何比较第一个列表中的每个元素和第二个列表中的整个元素？

Question

I'm very new to python, so I need your help . I have csv file contains:

  Name           Movie_title            Comments
  Mark           toy story                love
  Sam            Grumpy Old Men           cool 
  Mark           Grumpy Old Men           Hate it
  Sam            toy story                didn't like it

I create a list contains only name without duplicate: names = ['Mark,Sam'] so what I want to create a text file with movie_title(eg, toy story.txt) contains all the comments in that movie

toy story.txt

Mark -- toy story (love the movie)
Sam -- toy story (didn't like it)

Grumpy Old Men.txt

Sam -- Grumpy Old Men (cool)
Mark -- Grumpy Old Men (Hate it)

with open('data.csv', 'rt') as f:
 reader = csv.reader(f, delimiter=',')
  next(reader)# skip header
  for row in reader:
    for name in names:
       if name == row[0]:
         for i in row[0]:
          txt = open(os.path.join(dir_name, names + ".txt"),'w+')
          newlist.append(name+row[2])
          txt.write(newlist)

any idea !!!!

Answer 1

A bit simpler. Because each line has the fields name, movie and comment (row[0], row[1] and row[2], respectively), you can just directly write everything from the fetched line:

#!/bin/python
import csv
with open('data.csv', 'rt') as f:
  reader = csv.reader(f, delimiter=',')
  next(reader)# skip header
  for row in reader:
    with open(row[1]+".txt","a") as mov:
      mov.write(row[0]+" -- "+row[1]+" ("+row[2]+")\n")
