benfred/py-spy (via) A Python port of Julia Evans’ rbspy profiler, which she describes as “probably better” than the original. I just tried it out and it’s really impressive: it’s written in Rust but has precompiled binaries so you can just run “pip install py-spy” to install it. Shows live output in the terminal while your program is running and also includes the option to generate neat SVG flame graphs.
