python处理csv文件

csv read

import csv
f = open(‘see.csv’,’r’)
reader = csv.reader(f)
for line in reader:
print(line)

csv write

import csv
f = open(‘see1.csv’,’w’)
writer = csv.writer(f)
writer.writerow([‘user_id’, ‘shop_id’, ‘time_stamp’, ‘longitude’, ‘latitude’, ‘wifi_infos’])
f.close()
如果是想在文件末尾添加，那就把w改为a就可以来
