Can calling Python scripts with Go or Rust break through GIL restrictions to achieve true parallel execution?

Can Go or Rust implement parallel processing bypassing GIL by calling Python scripts?

The performance bottleneck of Python projects is often its global interpreter lock (GIL). To improve performance, one approach is to use Go or Rust to call Python scripts, thereby leveraging multi-process parallelization to circumvent GIL limitations.

Go can be packaged through the os/exec package, and Rust can start a standalone Python process through std::process::Command . Each Python process has its own GIL, so it can be executed in parallel without being affected by a single process GIL.

Communication between Go or Rust and Python processes requires inter-process communication (IPC) mechanisms, such as pipelines or shared memory, to ensure data exchange and task coordination, thereby enabling efficient parallel processing.

This cross-language call and multi-process parallel strategy can significantly improve project performance while leveraging existing Python code.
