我有一个CSV文件,其中包含我需要提取的某些列.其中一列是一个文本字符串,我需要从中提取第一个和最后一个项目.我在for循环中有一个print语句,它正是我所需要的,但却无法弄清楚如何将这些数据放入列表或dict中.不确定哪个是最好用的.
代码到目前为止:
f1 = open ("report.csv","r") # open input file for reading
users_dict = {}
with open('out.csv', 'wb') as f: # output csv file
writer = csv.writer(f)
with open('report.csv','r') as csvfile: # input csv file
reader = csv.DictReader(csvfile, delimiter=',')
for row in reader:
print row['User Name'],row['Address'].split(',')[0],row['Last Login DateTime'],row['Address'].split(',')[7]
users_dict.update(row)
#users_list.append(row['Address'].split(','))
#users_list.append(row['Last Login DateTime'])
#users_list.append(row[5].split(',')[7])
print users_dict
f1.close()
从文件输入:
User Name,Display Name,Login Name,Role,Last Login DateTime,Address,Application,AAA,Exchange,Comment
