问题
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?
回答1:
Here is screenshot of my Pycharm. Required settings is in following path: File -> Settings -> Editor -> Code Style -> General: Right margin (columns)
回答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.

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

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. :)

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 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.
