python - How do I set the maximum line length in PyCharm?

Question

I am using PyCharm on Windows and want to change the settings to limit the maximum line length to 79 characters, as opposed to the default limit of 120 characters.

Where can I change the maximum amount of characters per line in PyCharm?

Answer 1

Here is screenshot of my Pycharm. Required settings is in following path: File -> Settings -> Editor -> Code Style -> General: Right margin (columns)

Answer 2

For PyCharm 2018.1 on Mac:

Preferences (⌘+,), then Editor -> Code Style:

For PyCharm 2018.3 on Windows:

File -> Settings (Ctrl+Alt+S), then Editor -> Code Style:

To follow PEP-8 set Hard wrap at to 80.

Answer 3

For PyCharm 4

File >> Settings >> Editor >> Code Style: Right margin (columns)

suggestion: Take a look at other options in that tab, they're very helpful

Answer 4

You can even set a separate right margin for HTML. Under the specified path:

File >> Settings >> Editor >> Code Style >> HTML >> Other Tab >> Right margin (columns)

This is very useful because generally HTML and JS may be usually long in one line than Python. :)

Answer 5

For anyone, or myself if I reload my machine, who this is not working for when you do a code reformat there is an additional option to check under editor->code style->python : ensure right margin is not exceeded. Once this was selected the reformat would work.

Answer 6

For PyCharm 2017

We can follow below: File >> Settings >> Editor >> Code Style.

Then provide values for Hard Wrap & Visual Guides for wrapping while typing, tick the checkbox.

NB: look at other tabs as well, viz. Python, HTML, JSON etc.

For PyCharm 2019.3.1, I see this.
