For my personal Python projects I set a hard limit in the 94-96 range. That's wide enough that I actualy adhere to it instead of just ignoring it.
PEP8's and Google style guide's limits of 79 and 80 are way to narrow for a language with 4 space identation. However PEP says that "it is okay to increase the line length limit up to 99 characters" while Google's 80 is just a soft limit that can be broken in certain cases like long URLs.
