file that specifies a Python version.python app.py
If you run your app with python app.py
and close your
browser, the process may continue running in the background. When
you reopen your workspace and run python app.py
, you may find
that this fails as the previous app is still running. You may not
be able to terminate the previous process with ctrl+C
as the previous
terminal view may not be available. To terminate the previously running
Python process, either:
Save your files, add your recently installed packages to requirements.txt
, and restart your workspace.
List the Python processes with $ ps aux | grep
python
. Then, run $ pkill <pid>
on the process IDs. For example,
you might see:
shell
$ ps aux | grep python
