How can I use memory profiler in Python?

You can use the memory_profiler module to monitor memory usage in your Python scripts. Would you like a quick setup guide?

Yes, please provide the setup steps.

First, install the module using pip: pip install memory-profiler. Then, you can use the @profile decorator to mark 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:

from memory_profiler import profile

@profile
def my_function():
    a = [1] * (10 ** 6)
    b = [2] * (2 * 10 ** 7)
    del b
    return a

my_function()

Run this script with python -m memory_profiler your_script.py to see the memory usage.

What if I want to analyze a script without modifying it?

You can run your script with the command python -m memory_profiler your_script.py directly in the terminal, which will profile the entire script.
