What are some examples of using line_profiler in Python?

Can you give me some examples of how to use line_profiler in Python?

Sure! Line_profiler is a great tool for profiling the execution time of individual lines of code in Python. For example, you can use it to analyze a function like this:

@profile
def my_function():
    total = 0
    for i in range(10000):
        total += i
    return total

You would run this with the command kernprof -l -v my_script.py to see the line-by-line execution time.

How do I install line_profiler?

You can install line_profiler using pip. Just run the command pip install line_profiler in your terminal.

Can I use line_profiler with Jupyter notebooks?

Yes, you can use line_profiler in Jupyter notebooks! You can use the %load_ext line_profiler magic command to load it and then use the @profile decorator on your functions.

What are some common use cases for line_profiler?

Common use cases include optimizing performance-critical functions, identifying bottlenecks in your code, and comparing the efficiency of different algorithms.
