如何从csv打印出json数据

import csv
import json

csv_file = open('data.csv', 'r')
csv_reader = csv.reader(csv_file)
data_list = list(csv_reader)
csv_file.close()

header = data_list[0]  # 获取csv文件的标题行
json_data = []  # 存储转换后的json数据

for row in data_list[1:]:
    json_row = {}  # 存储每一行的数据
    for i in range(len(header)):
        json_row[header[i]] = row[i]  # 将每一行的数据与标题对应
    json_data.append(json_row)

json_str = json.dumps(json_data, indent=4)
print(json_str)
