In a terminal, a student types python hello.py and gets an error that the file cannot be found. The file is in the folder Documents. What should the student do? Which commands help?
Need a reminder? The key ideaShow
The terminal looks for the file in its own folder. Use cd to go to the folder of the file.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, compare your working with the solution.
The terminal is probably in a different folder from the file.
- Go to the folder:
cd Documents. - Check that the file is there:
diron Windows, orlson macOS and Linux. - Run it again:
python hello.py(orpy hello.pyon Windows, orpython3 hello.pyon macOS and Linux).
Answer: use cd to go into the folder, check with dir or ls, and run it again.
