If I were to do
age, height = 16, 1.24
would that be faster than
age = 16
height = 1.24
It would be a very small difference, but I imagine if you are declaring many variables, that time will add up.

1Does this answer your question? [More elegant way of declaring multiple variables at the same time](https://stackoverflow.com/questions/5495332/more-elegant-way-of-declaring-multiple-variables-at-the-same-time) – Dec 20 '20 at 05:27

2No, it does not. I want optimization, not elegance. – Dec 20 '20 at 05:29

Sorry, I don't see where. – Dec 20 '20 at 05:32

Ok I see but in my opinion both are same. – Dec 20 '20 at 05:33

Your opinion is that optimization = good looks? – Dec 20 '20 at 05:34

Have you tried timing it? – juanpa.arrivillaga Dec 20 '20 at 05:36

Didn't know that was a thing, thanks! – Dec 20 '20 at 05:38

1Yes, you can use the timeit module. Although you are looking for a needle in haystack performance improvements. On my machine, I found the latter one (declaring across multiple lines) was faster – Naman Dec 20 '20 at 05:58

1Single line will probably be slower since a tuple will be created and then unpacked – Iain Shelvington Dec 20 '20 at 06:04

import timeit
code1 = 'age, height = 16, 1.24'
code2 = '''age = 16
height = 1.24'''
print (timeit.timeit(stmt = code1, number = 1))
print (timeit.timeit(stmt = code2, number = 1))
I think declaring each variable separately would be much faster. Try seeing that with the help of the code above.

On my computer, both ways of assigning took the same amount of time, 14.5ns. – Michael Scott Asato Cuthbert May 02 '22 at 21:42
