Hello,

It turns out that you are running your python file a folder before RD2, which ends up defining the project root as the folder containing the folder RD2. (I believe it’s running on Vscode)

So when you use the with open('data.csv'), it looks for the file at the root. And, as it doesn’t really exist in that folder, it will give the error.

If you play the data.csv out of RD2, the execution will take place normally. Or you put with open('RD2/data.csv') as _file: which will also work! :)

  • Thank you, now it’s working

  • You’re welcome, @Brunoluizbender :)

  • If possible, mark the answer as a solution for others to see that the question has already been answered :)
