如何在python中将csv转换为json？

Question

我对编程非常陌生，过去3/4星期一直在学习python，这是给出的作业之一。

输入项

A, B, C, D
1, 2, 3, 4
5, 6, 7, 8

输出量

{{A:"1", B:"2", C:"3", D:"4"}, {A:"5", B:"6", C:"7", D:"8"}}

我一直在尝试代码为：

import csv
import json

csvfile = open('test.csv','r')
jsonfile = open('test.json','w')

x = ("a","b","c","d")

reader = csv.DictReader(csvfile, x)
for row in reader:
    json.dump(row, jsonfile)

此代码的输出如下：

{"a": "1", "null": ["5", "6", "7", "8", "9"], "c": "3", "b": "2", "d": "4"}

谁可以帮我这个事？

处理完整行后转储。

import csv
import json

with open('test.csv') as f:
    reader = csv.DictReader(f)
    rows = list(reader)

with open('test.json', 'w') as f:
    json.dump(rows, f)
