The problem is that you have another file in your directory called csv.py. And in this file you do not have a readerfunction.
问题是您的目录中有另一个名为csv.py. 在这个文件中你没有一个reader函数。
Change its name to my_csv.py
将其名称更改为 my_csv.py

- 'csv' is an in-built package. So you dont have to install it again in Pycharm.
- When you try to import csv, make sure that you dont have any file(created by you) named as 'csv.py' in your project folder(or Python Path Variable folders) because of this you are not actually importing 'csv' package.
- 'csv' 是一个内置包。所以你不必在 Pycharm 中再次安装它。
- 当您尝试导入 csv 时，请确保您的项目文件夹（或 Python 路径变量文件夹）中没有任何名为 'csv.py' 的文件（由您创建），因为您实际上并未导入 'csv' 包.
