4/5 finals left till I start my last year of pharmacy school.

The suspense is killing me.

APPE Rotations secured.

Three clinicals, an interesting hospital-like elective, supermarket retail, and an institutional rotation by my house. I am excited I got my first choices, and the timings are great as well.

List comprehension or mapping?

I have asked this question quite a few times in the past. Which would be better? List comprehension, or a map function to convert every item in a list or tuple to another?

Upon Googling, you will get very different answers from different people.

Let's try it with the timeit module.

".".join([str(x) for x in range(20)]) ".".join(map(str, range(20))

As you can see, both lines use range(20) to create a generator of 20 integer values. Then, either the map function, or the list comprehensor loops through the list converting each value to a string and returning the new value.

These are the results I found:

spike@Jacob-Laptop MINGW64 ~ $ python -mtimeit "'.'.join(map(str, range(20)))" 100000 loops, best of 3: 4.27 usec per loop spike@Jacob-Laptop MINGW64 ~ $ python -mtimeit "'.'.join([str(x) for x in range(20)])" 100000 loops, best of 3: 5.64 usec per loop

So which one of these is the best method?

Turns out, using map() was slightly faster. But, after trying this, I realised there was another option. Using a tuple directly. This should save the interpreter a little memory footprint, but in larger cases this would scale.

".".join(tuple(str(x) for x in range(20)))

spike@Jacob-Laptop MINGW64 ~ $ python -mtimeit "'.'.join(tuple(str(x) for x in range(20)))" 100000 loops, best of 3: 6.21 usec per loop

Wew lenny! (╯°□°) ╯︵ ┻━┻

That is a lot slower than I would have expected. Looks like map() is still king, in terms of speed.

All tests results were taken from timeit using best of three 100,000 loop tests.

My GPA is looking pretty nice!

Thanks, electives!
