How to save data into next columns

[wavic]

It's about how you construct your data.

>>> import csv
>>> data = [['a', 123, 123,123], ['b', 345, 345, 345]]
>>> with open('/tmp/data.csv', 'w') as output:
...     writer = csv.writer(output)
...     for row in data:
...         writer.writerow(row)
... 
15
15
>>> with open('/tmp/data.csv', 'r') as data:
...     for line in data:
...         print(line)
... 
a,123,123,123

b,345,345,345
