csv Creation Failure

[XanderXueMingJi]

python --version: 3.7.0
chapter5/2-createCsv.py

Hello, I write the code according to the content on github, and even copy and paste the code directly afterwards, so that I can control the platform to report errors:
FileNotFoundError: [Errno 2] No such file or directory: '../files/test.csv'
Can you tell me how to solve the problem?

@XanderXueMingJi you need to make sure that you have parent directory(with this name files) of your current directory. Only then it will work.
