I don&#x27;t contribute to many open-source projects. But I&#x27;d imagine Python would have a good track record, PEP8 specifies something like a 72-character limit.<p>That said, long lines in an existing project aren&#x27;t a dealbreaker, if I have other reasons for contributing. (The one I&#x27;m working on now has them.) But if there&#x27;s no reasonable way for me to write code in a language <i>without</i> breaking 80 chars, I&#x27;m not likely to choose that language for my own projects.
