python中csv的读取

先创建商品列表，然后写入创建表头
再写入一段新的数据，将新的数据中的“；”
换成“|"进行分割

import csv

productList = [{
        "sku": 1,
        "name": "iphone 12 pro max",
        "price": 12999,
        "brand": "苹果"
    }, {
        "sku": 2,
        "name": "mate 40",
        "price": 7999,
        "brand": "华为"
    }, {
        "1sku": 3,
        "name": "vivo r9",
         "prbcxice": 3999,
        "brand": "vivo"
    }]

    list_new = []
    print(list)
    for obj in list:
        list_new.append([obj["sku"],obj["name"],obj["price"],obj["brand"]])
    print(list_new)

    with open("data.csv",'w',encoding='utf8') as csvFile:
        writer = csv.writer(csvFile)
        writer.writerow(["sku","名字","价格","品牌"])
        writer.writerow(list_new)

    with open("data1.csv",'w',encoding='utf8',newline='') as csvFile:
        #存储csv，拿到writer对象
        writer = csv.DictWriter(csvFile,["sku",'name',"price","brand"])
        #writer.writeheader()
        writer.writerows(list)
write_csv_dic(productList)

    mywriter.writerow(["江苏省|淮安市|清江浦区"])
