Python：在csv文件中写入输出

Question

I have the following text (as string, \\t = Tab): Article_1 \\t Title of Article \\t author of article \\n Article_2 \\t Title of Art 2 \\t author of article 2 \\n

I'd like to save this in a csv-file st I can open it in Excel. In fact, it is possible to open the file I got in Excel, but the program writes everything in the first column, but I'd like to have "art_1, art_2, ..." in the first column, the titles in the second and the authors in the third column. How can I do this?

Thanks for any help! :)

Answer 1

If you have a string, str , one easy way is just:

with open("file.csv","w") as f:
    f.write(','.join(str.split()))

If you have multiple strings, and they are stored in a list, str_list , you could do this:

with open("file.csv","w") as f:
    for line in str_list:
        f.write(','.join(line.split()))
        f.write('\n')

If the question is how to split one monolithic string into manageable sub-strings, then that's a different question. In that case you'd want to split() on the \\t and then go through the list 3 at a time.

There's also a csv python package that provides a clean way of creating csv files from python data structures.

Answer 2

In case you want to use the csv module

import csv

with open("csv_file.csv", "wb") as csv_file:
  csv_writer = csv.writer(csv_file, delimiter=",")
  for str in list_of_articles:
    csv_writer.writerow(str.split("\t"))
