python3 cvs将数据读取为字典

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)
