cProfile vs Line Profiler: Which One to Use?

What are the main differences between cProfile and Line Profiler?

cProfile is a built-in Python profiler that provides a high-level overview of function calls, while Line Profiler focuses on line-by-line execution time for more granular insights.

When should I use Line Profiler instead of cProfile?

Use Line Profiler when you need detailed performance analysis of specific functions, especially if they are complex or time-consuming.

Can I use both profilers together?

Yes, you can use both profilers together to get a comprehensive view of your code's performance, combining high-level and detailed insights.

Are there any performance overheads when using these profilers?

Yes, both profilers introduce some overhead, but cProfile is generally more efficient than Line Profiler due to its sampling method.
