在Pycharm（Python 3.8）上运行python文件时出现问题

Question

我编写了一个python文件，执行后应在本地目录中创建一个csv文件。即使执行成功完成，python文件也不会在本地目录中创建csv文件。我的代码和输出屏幕截图如下：

SELECT ed.monthNameYear, ed.monthName,        
       COUNT(*),
       SUM(COUNT(*)) OVER (ORDER BY ed.monthNameYear)
FROM (SELECT DATE_FORMAT(`reservation_for`,'%Y-%m') as monthNameYear,
             DATE_FORMAT(`reservation_for`, '%M %Y') as monthName, 
             email,
             COUNT(*) AS cnt
      FROM `tablename`
      GROUP BY email, DATE_FORMAT(`reservation_for`, '%Y-%m'),
            DATE_FORMAT(`reservation_for`,'%M %Y')
      HAVING COUNT(*) > 1 
     ) ed
GROUP BY ed.monthNameYear, ed.monthName;

由于当前工作目录（cwd）问题，很有可能将其保存在您不希望的地方。

按照PyCharm current working directory更改PyCharm中的当前工作目录，或使用代码明确更改它：

import os # put these lines at the top of your script
os.chdir(r"/Users/bsulin/PycharmProjects/StockNewsWebScraper/")
