Collection of Python code for using in lab environment (data acquisition, device communication, data analysis)

Project description

PyLabLib is a collection of code intended to simplify some of the coding tasks encountered in a physics laboratory.

Some major parts include:
  • Simpler loading and saving of data in text or binary files.

  • Data tables with heterogeneous columns and more universal indexing (heavy overlap with pandas).

  • Some data processing utilities: filtering, decimating, peak detection, FFT (mostly wrappers around NumPy and SciPy).

  • Classes for device control (universal wrapper for pyVISA, pySerial and network backends).

  • Classes for many specific devices (cameras, lasers, translation stages, etc).

  • More user-friendly fitting interface.

  • Multi-level dictionaries which are convenient for storing heterogeneous data and settings in human-readable format.

  • A bunch more utilities dealing with file system (creating, moving and removing folders, zipping/unzipping, path normalization), network (simplified interface for client and server sockets), strings (serializing and de-serializing values), function introspection, and more.

  • Additional tools for GUI generation and simpler multithreading built on top PyQt5 (still in development stage: not completely documented, code organization and interfaces can change in later versions).

The most recent version library is available on GitHub (, and the documentation can be found at .

For a more comprehensive, specialized, and recent version of the library (also specific dll’s required for some devices), check out dev branch of the GitHub repository.
