This is a frequent and IMHO mostly weird question. I understand the "why reimplement XYZ in $YOURFAVORITELANGUAGE just to have XYZ in $YOURFAVORITELANGUAGE" sentiment but there is an equally valid benefit in using uniform tool stacks. I am a Python developer. I am comfortable working in other languages, and contributing patches to tools written in other languages, but there is a real benefit to having a full toolset written in a single language even if some of those tools are less developed than their counterparts. This is besides the benefit that even though you might not need tmux in Python, having tmux in Python might have created tmux-the-library which someone might later need. (I haven't yet tried this but I plan on doing so. On an unrelated note, thanks to the author for making this pure Python, and for caveatting "it's not as fast as C" with "but try PyPy").
