How can I use line profiler to optimize my Python code?

You can use the line_profiler package to measure the execution time of individual lines in your Python functions. First, install it using pip.

What are the steps to install line_profiler?

You can install line_profiler by running pip install line_profiler in your terminal. After that, you can use the @profile decorator on the functions you want to analyze.

Can you show me an example of how to use the @profile decorator?

Sure! Here’s a simple example:

@profile
def my_function():
    # Your code here

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

What kind of output should I expect from line_profiler?

You will get a detailed report showing the time spent on each line of the decorated function, helping you identify bottlenecks.
