Python can't execute test.py

[agileqatester]

Hi,
I am trying to follow your training and I am at v0.5 when I need to run a Unit Test python app test.py.
I am using docker on windows.
When I run "docker-compose up -d"
I see that python app.py exited. I look at logs "docker logs 78cd1643a3bd" and see "python: can't open file 'app.py': [Errno 2] No such file or directory". The same error when I run "docker-compose run dockerapp python test.py"
Thanks in advance
