Producing CSV

CSV文件即为有逗号（，）隔开的记录格式文件（Commas Separated Values）。

Year,Unruly Airline Passengers
1995,146
1996,184
1997,235
1998,200
1999,226
2000,251
2001,299
2002,273
2003,281
2004,304
2005,203

在Django中使用CSV，用法如下

import csv
from django.http import HttpResponse

# Number of unruly passengers each year 1995 - 2005
UNRULY_PASSENGERS = [146,184,235,200,226,251,299,273,281,304,203]

def unruly_passengers_csv(request):
    # Create the HttpResponse object with the appropriate CSV header.
    response = HttpResponse(mimetype='text/csv')
    response['Content-Disposition'] = 'attachment; filename=unruly.csv'

    # Create the CSV writer using the HttpResponse as the "file"
    writer = csv.writer(response)
    writer.writerow(['Year', 'Unruly Airline Passengers'])
    for (year, num) in zip(range(1995, 2006), UNRULY_PASSENGERS):
        writer.writerow([year, num])

    return response
