Use cProfile/Profile to profile the performance of code

import cProfile

# Use `profile` if `cProfile` isn't available on your OS
# import profile


def adder(x, y):
	return x + y


cProfile.run('adder(10, 20)')

#performance #python

Use timeit to benchmark code

import timeit


def adder(x, y):
	return x + y


t = timeit.Timer(setup='from __main__ import adder', stmt='adder(10, 20)')
t.timeit()

Memory Dev Tools

# A memory leak can occur in your application when an element is no longer attached to the Document Object Model (DOM) tree, but is still referenced by some JavaScript running on the page. These elements are called detached elements.
[https://docs.microsoft.com/en-us/microsoft-edge/devtools-guide-chromium/memory-problems/dom-leaks]
 
 
 a reference to an object will prevent the object referenced from being garbage collected.

 # window leaks
 variables set on the window do not get collected
 - windwo.myvar = 'whatever'
