Memory profiling in python checking code memory usage 2021

okay, let's dive deep into memory profiling in python in 2023 (since the request was for 2021, this is the most up-to-date information). we'll cover several tools, techniques, and best practices to identify memory bottlenecks in your code and optimize its memory footprint.

**why memory profiling matters**

in many python applications, especially those dealing with large datasets, complex computations, or long-running processes, memory usage can become a significant bottleneck. excessive memory consumption can lead to:

* **performance degradation:** as memory fills up, the system might start swapping data to disk, which is drastically slower than ram.
* **out-of-memory errors:** your application can crash if it tries to allocate more memory than is available.
* **scalability issues:** an application that consumes too much memory per user/request will struggle to handle increased load.

**tools for memory profiling**

several excellent python tools can help you analyze memory usage. here are the most popular and effective ones:

1. **`memory_profiler`**

* **description:** a line-by-line memory profiler. it allows you to see the memory usage of each line of code within a function. this is incredibly valuable for pinpointing exactly where memory is being allocated.
* **installation:**



* **usage:**



* **running with `mprof`:**




or if you have `mprof` installed:

`mprof` displays a graph of memory usage over time, which can be very helpful in visualizing memory allocation patterns.
