python3 cvs将数据读取为字典的方法

import csv
with open("csv.csv",'r',encoding="utf-8") as f:
 reader = csv.reader(f)
 fieldnames = next(reader)#获取数据的第一列，作为后续要转为字典的键名 生成器，next方法获取
 # print(fieldnames)
 csv_reader = csv.DictReader(f,fieldnames=fieldnames) #self._fieldnames = fieldnames # list of keys for the dict 以list的形式存放键名
 for row in csv_reader:
  d={}
  for k,v in row.items():
   d[k]=v
  print(d)
