[Tutor] exporting lists into CSV issue.

[mhysnm1964 at gmail.com]

All,

 

I have addressed the issue. When I open the file, I am using newline='' as
one of the parameters. 

 

with open ('books-list.csv', 'w', newline='', encode='utf-8') as wf:

 

I added the UTF-8 as I discovered after sending my original email I was not
importing all the books. I discovered I was getting an utf-8 error due to
some of the content. Now I have all my books in a spreadsheet. Stage 2, is
to cross reference all this information against my audible library which I
will have to extract.

 

All this is to learn the different methods of extracting data.

Subject: exporting lists into CSV issue.

 

All,

 

Thanks in advance for any assistance. This is a follow up msg from my iTunes
import issue with the xml. I have managed to successfully import the data
from the XML with Peter's and Alan's help. I have moved the information into
a list and only extracting the data I want. Now I am trying to export to a
CSV file. There is no syntax or logical errors I can see. The information is
being exported to the CSV. But when I bring it into Excel. I am getting a
blank row between each row. The exported data looks like this:

 

Name,Artist,Kind,Total Time,Year,Date Modified,Date Added,Bit Rate,Sample
Rate,Comments,Location "In Her Sights: A Montgomery Justice Novel, Book 1

I would have expected a new line between each book, but there is a space.
The code looks like this:

 

import plistlib, pprint, csv 

 

with open("library.xml", "rb") as f:

    data = plistlib.load(f)

 

books =[['Name', 'Artist', 'Kind', 'Total Time', 'Year', 'Date Modified',
'Date Added', 'Bit Rate', 'Sample Rate', 'Comments', 'Location']]

 

for book in list(data['Tracks'].values()):

    tmp = []

    if not 'Audible file' in book['Kind']:

        break # skip book

    for key in books[0]:

        if key in book:

            tmp.append(book[key])

        else:

            tmp.append("")

    books.append(tmp)

 

with open ('books-list.csv', 'w') as wf:

    writer = csv.writer(wf)

    writer.writerows(books)

wf.close()

 

When I debug the above. The output of books look fine to me. For example:

 

(Pdb)
['Name', 'Artist', 'Kind', 'Total Time', 'Year', 'Date Modified', 'Date
Added', 'Bit Rate', 'Sample Rate', 'Comments', '
Location']
(Pdb)
(Pdb) books[0]

Any ideas why this could be occurring?
