cost of closure

tags: learning programming

content

comparing two functions:

with closure

def outer_func():
	def inner_func():
		pass
	return inner_func()

without closure

def func1():
	return _func1()
def _func1():
	pass

with closure
- all logic is in one code block, self-contained
- it’s creating a new function object inner_func every time outer_func is called, there’s a runtime cost
