PyShp


PyShp is a simple, pure Python library that reads and writes shapefiles. It doesn't do any geometry operations and only uses Python's standard library. It's contained in a single file that's easy to move around, squeeze onto small embedded platforms, and modify. It is also compatible with Python 3. It also implements __geo_interface__. The PyShp module is available on PyPI.

Let's repeat the previous OGR example with PyShp:

>>> import shapefile
>>> shp = shapefile.Reader("point")
>>> for feature in shp.shapeRecords():
...     point = feature.shape.points[0]
...     rec = feature.record[0]
...     print point[0], point[1], rec
...
