Total memory used by Python process?

Question

Is there a way for a Python program to determine how much memory it\'s currently using? I\'ve seen discussions about memory usage for a single object, but what I need is tot

Answer 1

Here is a useful solution that works for various operating systems, including Linux, Windows, etc.:

import os
import psutil
process = psutil.Process(os.getpid())
print(process.memory_info().rss)  # in bytes 

With Python 2.7 and psutil 5.6.3, the last line should be

print(process.memory_info()[0])

instead (there was a change in the API later).

Note: do pip install psutil if it is not installed yet.
