 with open('write.csv', 'r') as f: #打开
     text = csv.reader(f) #读取
     # print(text)
     for row in text:  #必须这样才可以读取出数据
         print(row)

     text = csv.DictReader(f) #以字典形式读取，会以第一行数据为代表
     print(text)
     for row in text: #必须这样才可以读取出数据
         print(row)

data = [[1,2,3,4,5],[1,2,3,4,5]]
with open('write.csv', 'w') as f: #创建
#     write = csv.writer(f) #录入·
#     for row in data:
#         write.writerows(row)

    write = csv.writer(f)  # 录入
