How can I use memory profiler in Python?

You can use the memory_profiler module to monitor memory usage in your Python scripts. First, install it using pip: pip install memory-profiler.

What are the main features of memory profiler?

Memory Profiler allows you to track memory usage line by line in your code, visualize memory consumption, and identify memory leaks.

Can you show me a simple example of how to use it?

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.

Is it possible to visualize the memory usage?

Yes, you can use the memory_profiler along with matplotlib to create visualizations of memory usage over time.
