calebmadrigal / for_loop.py

Last active September 24, 2015 15:48

Python for loop vs list comprehension speed test. This is just testing the speed of performing a particular operation in both a for loop and list comprehension. Note that the list comprehension version uses more memory because it is storing the results. This could be partially responsible for it being slower.

	import sys
	num = int(sys.argv[1])

	def test(i):
	return i+1

	for i in range(num):
	t = test(i)
