#读取和写入CSV文件
#引入CSV模块
import csv
#打开文件，注意：如果乱码，请在最后标明encoding的类型
with open("efg.csv","r",encoding='utf-8') as f:
    a_csv=csv.reader(f)#读出文件内容
#    print(list(a_csv))
    for row in a_csv:#用循环读出文件内容
        print(row)
#打开一个新的文件
with open("ee.csv","w") as f:
    #获得一个写入器
    b_csv=csv.writer(f)
    #一行一行的写
    b_csv.writerow(["ID","姓名","年龄"])
    b_csv.writerow(["1001","工藤新一","17"])
    c=[["1002","希希","18"],["1003","黑羽快斗","16"]]
    b_csv.writerow(c)
