How to get current CPU and RAM usage in Python?
How can I get the available and currently used memory from Python? It need to be cross-platform and at least work on at least Windows, Mac OS X and Linux.
I'd like to report the user in my application that he doesn't have enough memory free to proceed and do the next operation.

You can use it by putting the @profile decorator around any function or method and running python -m memory_profiler myscript. You'll see line-by-line memory usage once your script exits.
Use sys. getsizeof to get the size of an object, in bytes.
Python has a pymalloc allocator optimized for small objects (smaller or equal to 512 bytes) with a short lifetime. It uses memory mappings called “arenas” with a fixed size of 256 KiB.
to clear Memory in Python just use del. By using del you can clear the memory which is you are not wanting. By using del you can clear variables, arrays, lists etc.
You should take a look to psutil :
>>> import psutil >>> psutil.virtual_memory() svmem(total=16717422592, available=5376126976, percent=67.8, used=10359984128, free=1831890944, active=7191916544, inactive=2325667840, buffers=525037568, cached=4000509952, shared=626225152) If you love us?
