我无法弄清楚如何将此列表写入csv文件，python

Question

This is my code:

geometries = [[a, b, c], [d, e, f]] #Note I have lists within a list, this is required

with open("./datafiles/" + name, 'wb') as csvfile:
        writer = csv.writer(csvfile, delimiter=',', quotechar='|', quoting=csv.QUOTE_MINIMAL, lineterminator='\n')
        writer.writerow(geometries)

This code is meant to write the lists within geometries to a CSV file. The CSV file should look like this:

a, b, c

d, e, f

Instead I get a txt file that looks like this:

|['a', 'b', 'c']|,|['d','e','f']| 

How do I remove these ( | [ ] '' ) from the text file and have it displayed as above?

Answer 1

You want to use .writerows() not writerow() .

By using the correct function, it'll output your CSV file as you expect.

The issue you have with the lines showing on the same row in some editors is due to your lineterminator . You are setting it to \\n , instead of the default \\r\\n

Answer 2

.writerow() expects a flat list as a parameter. To write a list of rows at once use .writerows() :

geometries = [[a, b, c], [d, e, f]] 

with open("./datafiles/" + name, 'wb') as csvfile:
    writer = csv.writer(csvfile, delimiter=',', quotechar='|',
                        quoting=csv.QUOTE_MINIMAL, lineterminator='\n')
    writer.writerows(geometries)
