使用 Python csv writer 附加到 csv 文件的问题

Question

I am trying to append on a row of 3 data points to an existing csv file.

import time
import csv
data = [[time.strftime("%m/%d/%Y"), 10, 122]]

with open('C:\myfile.csv', 'a') as f:
    writer = csv.writer(f)
    writer.writerows(data)

The data comes out like this:

1   0   /   1   9   /   2   0   1   5
<blank row>                             
10/19/2015  10  122                         
<blank row>                             
10/19/2015  10  122                         

The original CSV file looked like this:

10/17/2015  120  22
10/18/2015  110  2

Expected to just add this:

10/19/2015  10  122 

Answer 1

import time
import csv
data = [[time.strftime("%m/%d/%Y"), 10, 122]]

with open('C:\myfile.csv', 'a', newline = '') as f:
    writer = csv.writer(f)
    writer.writerows(data)
