Automatically add newline on save in PyCharm?

PyCharm 5 complains of a missing newline at the end of the file:

PEP 8: No newline at end of file

How do I tell PyCharm to add the newline (if missing) automatically whenever I save a file?

Solution 1:

This can be enabled in the Editor > General settings:

From the File menu open the Settings and select Editor > General. Under the Other section in the right-hand pane, check the Ensure an empty line at the end of a file on Save setting.

Ensure an empty line at the end of a file on Save (PyCharm PE 2020.1.3)

Solution 2:

Newer PyCharm I believe (2020+):

Solution 3:

PyCharm 2021.1

You can now find this setting here:

Settings > Editor > General > Ensure every saved file ends with a line break.

Solution 4:

What I usually do is I create a macro to do three things:

Reformat code
Organise imports
Save all files

This will, indeed, add a newline at the end of each file. Then I rebind the Save all shortcut (Cmd+S on Mac) to this macro.

You can read more about macros here. I also recommend using Navigate to Action to find actions you forget the hotkeys for.
