It acts as a backend to the pyvisa package, translating high-level instrument commands into low-level communication over Serial, USB, GPIB, and Ethernet interfaces. The package uses well-maintained cross-platform Python libraries (PySerial, PyUSB, etc.) to handle the actual I/O, making it portable across Windows, macOS, and Linux.\n\nTypical use is in measurement automation, data acquisition, and laboratory control scripts where you need to query or command instruments without vendor lock-in. You install it, tell pyvisa to use the '@py' backend, and then use standard VISA resource names to open connections to instruments. Optional dependencies unlock additional features like GPIB support, device discovery, and proprietary protocols.","worth_installing":"Yes, if you need to control laboratory instruments via VISA and want to avoid proprietary library dependencies. The package is actively maintained, has low install friction, carries a permissive MIT license, and supports current Python versions. Install it as a pyvisa backend when vendor VISA libraries are unavailable or when cross-platform portability is required. No known vulnerabilities as of the fact sheet date."},"id":"pyvisa-py","links":{"html":"https://skillfed.io/packages/pyvisa-py","md":"https://skillfed.io/packages/pyvisa-py.md","pypi":"https://pypi.org/project/pyvisa-py/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-09-04","license_spdx":null,"license_treatment":"permissive","name":"PyVISA-py","python_support":"supports_current","summary":"Pure Python implementation of a VISA library."},"popularity":{"monthly_downloads":849120,"position":4909,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.8.1"}
