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?

PEP 8 suggests lines should be limited to 79 characters. This is because it allows you to have multiple files open next to one another, while also avoiding line wrapping. Of course, keeping statements to 79 characters or less is not always possible.
Traditional line length research, limited to print-based text, gave a variety of results, but generally for printed text it is widely accepted that line lengths fall between 45 and 75 characters per line (cpl), though the ideal is 66 cpl (including letters and spaces).
Maximum line length PEP 8 guides us to limit all lines to max 79 characters: https://www.python.org/dev/peps/pep-0008/#maximum-line-length. Comments (multi-line or single line) should be limited to 72 characters. We use a line length limit of 88 characters on this website.
The Python standard library is conservative and requires limiting lines to 79 characters (and docstrings/comments to 72). The preferred way of wrapping long lines is by using Python's implied line continuation inside parentheses, brackets and braces.
Here is screenshot of my Pycharm. Required settings is in following path: File -> Settings -> Editor -> Code Style -> General: Right margin (columns)
