Be a Python Pro with Enumerate

Enumerate is an important built in function in #python and #coding folks should know how to use it. Don't be a noob!

[jackmillen]

Ngl, calling people a noob is kinda a noob thing to do

Frankly, as long as you write clean, readable code, you're a pro to me, regardless of your knowledge of python's forensics. ❤️

The other two ways are perfectly acceptable in other languages and may even be easier to read so I have no issue with them.

I've been coding python for more decades than I care to admit and if someone used the first two I wouldn't think they're "noobs", it's perfectly fine. Or conversely, that using the enumerate function is anything to show off about.

The fact you think it's advanced says more about you than anything else.

Don't be a noob, don't code in python :)

meanwhile c/c++, c#, java, js and many others:

"iterating over a list? nah havent heard of it"

[blaze_eagle]

But why is it so much better?
Does it help improve Data management? Is it faster? does it have any substantial advantege against just going through an Loop with the iterable Object range?

I see you have spiced thing up come 2023. It is fun to watch. Love to see you work hard everyday with all the shorts and streams. I see that the freq of streams have increased. This motivates me to work harder! Thank you GM!!

[TheVergile]

the real noob thing would be to not mention why this would be better and why people should care

[Alee_Calee]

This was really helpful for my 5th grade python on-paper test, thx!

Enumerate looked so complicated to me at first when I was a total beginner. Now I kinda feel stupid, it's super easy. But feeling stupid is part of being a programmer I guess.

C language family devs: look at what they need to do to mimic a fraction of out power!

[JoeBob]

Really? Youre going to shame people for using the "for i in range"?

It is a core concept in Python, and does exactly what it needs to. Can you give a technical reason for *why* you shouldnt use "for i in range"?

[fingerman]

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

[llambduh]

If your only goal was to take a list, give it indexes, and print it you could just do this:



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.

“Sorry the counter method is just because I’m so used to writing assembly in embedded systems, take that noob”

[bgxhylo]

as a c++ user, i find it hard to believe this isn't common knowledge lmao

[christophercarillo]

Me watching the video:
Doesn't enumerate come from itertools tho?
Me after a quick Google search:
Oh nice, it's a built-in function

[godbernaz]

Im just starting and I had to do something similar today for my work and this appears, thanks!

[adrisongomez]

I found it like 3 or 2 weeks ago by mistake and it’s really nice function
