How do I set up a line profiler for my Python application?

To set up a line profiler, you can use the line_profiler package. First, install it using pip: pip install line_profiler.

What do I do after installing it?

After installation, you need to decorate the functions you want to profile with @profile. Then run your script with kernprof -l -v your_script.py.

Can I profile multiple functions at once?

Yes, you can decorate multiple functions in your script with @profile, and they will all be profiled when you run the script.

What kind of output can I expect?

The output will show you the time spent on each line of the decorated functions, helping you identify bottlenecks.
