What is line profiling and how can it help my code?

Line profiling is a technique used to analyze the performance of your code by measuring the time each line of code takes to execute. It helps identify bottlenecks and optimize performance.

How do I implement line profiling in Python?

You can use the line_profiler package in Python. First, install it using pip, then decorate the functions you want to profile with @profile.

Can you show me an example of using line_profiler?

Sure! Here's a simple example:

@profile
def my_function():
    # Your code here

Run your script with kernprof -l -v your_script.py to see the profiling results.

What are some common pitfalls when using line profiling?

Common pitfalls include profiling code that is not representative of real usage, not considering the overhead of profiling itself, and misinterpreting the results.
