python：.csv文件乱写数据

Question

#write data in .csv file
def data_save_csv(type,data,id,name,header,since = None):
    #get the date when storage data
    date_storage()
    #create the data storage directory
    csv_parent_directory = os.path.join("dataset","csv",type,glovar.date)

    #write data in .csv

    with open(csv_file_directory,'w',newline='', encoding='utf-8') as csvfile:

                for k in data[i].keys():
                    if isinstance(data[i][k],bool):
                        data[i][k] = str(data[i][k])
                    row.append(data[i][k])

                row = [item['id'],item['permalink_url'],item['created_time'],item['updated_time'],item['from']['name'],item['from']['id'],item['message'],item['link'],item['likes']['summary']['total_count'],item['comments']['summary']['total_count']]

Write a python program to write data in .csv file, when the type is “user_feed”, I print the items of the data:

id=110286969468305_112459422584393,
permalink_url=https://www.facebook.com/110286969468305/posts/112459422584393,
created_time=2016-12-18T12:44:52+0000,
updated_time=2016-12-18T12:47:10+0000,
name=Dewi Nurfitri Oktaviani,
from_id=10202749157833181,
message=Hi, nice to meet you,
link=,
likes_total_count=0,
comments_total_count=1,

They are right, but when write the data in the .csv file, I found the sequence of the data does not match the head order, the head is :

header = ["POST ID", "Permalink", "Create time", "Updated time", "Author", "Author ID", "Message", "Link", "Likes", "Comments"]

and you can see that in this method "data_save_csv",

elif type == "group_feed" or "public_figure_posts" or "user_feed":
    feed = data
    for item in feed:
         #parse the feed data from group_download.py
         row = [item['id'],item['permalink_url'],item['created_time'],item['updated_time'],item['from']['name'],item['from']['id'],item['message'],item['link'],item['likes']['summary']['total_count'],item['comments']['summary']['total_count']]
         writer.writerow(row)

You can see that the sequence of the data item is the same with that in the head, but when I open the csv file, I found the sequence of the head item is right, but the sequence of the data item is disorder, no "id" data, and the other items order is not in the right order.

could you please help me?

Problem 1: This line

if type == "group_members" or "user_friends" or "user_likes":

isn't doing what you want. The expression always evaluates to True . Possible replacements:

if type == "group_members" or type == "user_friends" or type == "user_likes":

if type in ("group_members", "user_friends", "user_likes", ):

if type in {"group_members", "user_friends", "user_likes", }:

and this line

elif type == "group_feed" or "public_figure_posts" or "user_feed":

has the same problem. You should fix both lines and try again.
