Python 读写Excel文件

读取：

import csv

with open(r'D:\egg.csv', 'rb') as f:

    reader = csv.reader(f)

    for row in reader:

        print type(row)

        print row

写入csv文件，一列：

import csv

with open(r'D:\egg2.csv', 'wb') as csvfile:

    spamwriter = csv.writer (csvfile, delimiter=' ', quotechar='|', quoting = csv.QUOTE_MINIMAL)

    spamwriter.writerow(['a','1','1','2','2'])

    spamwriter.writerow(['b','3','3','6','4'])

    spamwriter.writerow(['c','7','7','10','4'])

写入csv文件，多列：

import csv

with open(r'D:\egg3.csv', 'wb') as csvfile:

    spamwriter = csv.writer (csvfile, dialect='excel')

    spamwriter.writerow(['a','1','1','2','2'])

    spamwriter.writerow(['b','3','3','6','4'])

    spamwriter.writerow(['c','7','7','10','4'])
