tmxlib is a Python library fo handling TMX tile maps. It serves a relatively specific purpose: making it easy to write scripts for automatic handling of TMX files.
If you aren’t familiar with TMX, or you just want to make some maps, install Tiled , a GUI editor, and play around with it. Tiled’s wiki and IRC channel are places to go if you have questions about the TMX format.
If you’re looking to use maps in a game, chances are tmxlib won’t help you much. Try pytmxloader , PyTMX , or one of the other projects listed on the Tiled wiki .
