Python examples

The source code for all these Python examples can be found under MRPT/mrpt_examples_py. Run them with python3 <script>.py once the MRPT Python bindings are installed (pip install mrpt3, the python3-mrpt packages, or source install/setup.bash after building from sources).

See also the Python API reference. C++ examples are here. A machine-readable index of all examples is available in examples.json.
