[@llambduh]

If your only goal was to take a list, give it indexes, and print it you could just do this: print(list(enumerate(todo_list))) You can lose the loop, it entails unnecessary overhead for loop control. You had unnecessary string manipulation with the call to the .title() which also cost time. The print function you use in the loop introduces overhead because of the underlying system calls it makes. Making multiple prints can be slower than a single print, especially if there's a lot of data to print.

[@fingerman4086]

Enumerate is awesome but sometimes you really just need an index, and so range(len(Object)) works just fine

[@msschubi]

But you get the index with enumerate? or did i get this wrong?

Well... Under the hood it's basically doing the same thing. I suppose the code is more pythonic, but it only really improves readability if you're familiar with enumerate. Still a neat tip.

[@nifegun]

creating a range of length whatever does seem a little silly, but the counter solution is just as good as enumerate tbh. Also I wouldn't necessarily consider any approach a noob. if you're just iterating over a short list, its not a big deal how you manage it. I'll worry about code when it counts lol

it’s on a jupyter notebook so it tend to run a bit slower than normal python (also loops in python are slow)

[@xsardas1999]

I'm a noob both in English and python but. Usually builtin functions in python are faster since they use lower level language. Thus when you use enumerate counters are being assigned in C. If you move this assignment into a python script by using variable inside the loop. You make it a tiny bit slower that cans tack for bigger lists. Same goes for len, you have to access index of the variable every time instead just getting it from the builtin function. And if you just need index and not content itself, you can always use throwaway variable "_"
