import csv

reader = csv.reader(file('your.csv', 'rb'))
for line in reader:
    print line

 

writer(csvfile[, dialect='excel'][, fmtparam])

参数表(略: 同reader, 见上)

例子:

import csv

writer = csv.writer(file('your.csv', 'wb'))
writer.writerow(['Column1', 'Column2', 'Column3'])
lines = [range(3) for i in range(5)]
for line in lines:
    writer.writerow(line)

import csv


writer = csv.writer(file('your.csv','wb'), delimiter=' ')
writer.writerow(['Column1', 'Column2', 'Column3'])
lines = [range(3) for i in range(5)]
for line in lines:
    writer.writerow(line)
