 The WPI Robotics Library ([WPILib](https://wpilib.org)) is the standard :term:`software library` provided for teams to write code for their FRC\ |reg| robots. WPILib contains a set of useful classes and subroutines for interfacing with various parts of the FRC control system (such as sensors, motor controllers, and the driver station), as well as an assortment of other utility functions.

 ## Supported languages
 
 There are three versions of WPILib, one for each of the three officially-supported text-based languages: WPILibJ for Java, and WPILibC for C++, and RobotPy for Python. A considerable effort is made to maintain feature-parity between these languages - library features are not added unless they can be reasonably supported for both Java and C++ (with the C++ able to be wrapped by pybind for Python), and when possible the class and method names are kept identical or highly-similar. Java, C++, and Python were chosen for the officially-supported languages due to their appropriate level-of-abstraction and ubiquity in both industry and high-school computer science classes.
