Which Python tool would you use to visualize an application’s call stack and identify performance bottlenecks?
- cProfile
- Gunicorn
- Pyflame
- Pygraphviz
Pyflame is a tool for profiling Python applications. It helps visualize the call stack and identify performance bottlenecks. cProfile (Option 1) is a built-in profiler, but it doesn't offer visualization. Gunicorn (Option 3) is a web server. Pygraphviz (Option 4) is for graph visualization, not profiling.
