Python vector packages implement community standards for vector encoding. While these can seem complex, tools exist for conversion into various forms, and many of the tools include common interfaces for seamles exchange of data across tools.
Packages exist for easily reading data from file-based and other serialized data formats.
Most of these packages involve a series of steps to handle data, such as stepping through features via a loop, etc. Most tools do one or a couple of things only. GeoPandas addresses these challenges by enabling operations on feature collections in one step and bundling multiple tools via a coherent interface that builds on Pandas.

2015-12: Plotting a GeoDataFrame with folium. Includes cool example of going from geodataframe.crs to projection information using pyepsg; plus reprojecting with geopandas to_crs method and serializing as GeoJSON to display in Folium! Including use of Carto basemaps in Folium.
