I JUST Found Out About This Python Trick! #python #coding #programming

How to use a step argument with a slice operation in Python!

[lightless]

i knew this i told my lecturer this once and he was impressed lol

[theninja]

Python: [start:end:stepsize]
Matlab: (start:stepsize:end)
My will to live: gone

[GRBSnatch]

[<starting index>:<ending index>:<step>]

This reminds me "range" function. Because the first number you'll write means at what point you will start from your list and the second one is where to end. The third one is how to count, like if you insert "1" it will go by every first item in the range, if you put "3" it will go through every third one, enc. It's really cool that you can do the same stuff but easier

So many tricks to achieve similar goals could be problematic.

Anyone trying to remember, slices work as [start:end:stride]

[edbertkhovey]

You can write print (a[::-1]) no need the b

I just learned this this morning on sololearn lol.

welcome to slicing of lists and tuples.

I stumbled on your acc few days back and honestly love it. Please keep making content.

You just discovered this???!!! 😮😮😮WOW, congrats, man!

[krzysiekstawarz]

thats basically why i picked python over c++ or java on my highschool ict exam, you can actually check eg. if input is palyndrome using [::-1] instead of writing whole function and wasting time on c/java syntax!

[marklandgraf]

b[-1::-2] is same as b[::-2]
b[-2::-2] gives every other backwards starting with 9 instead of 10

Have known this for a while. It comes in handy when working with endianness.

[IllusionEDM]

ITS LITERALLY IN THE DOCUMENTATIONS, EVEN I KNOW THIS AND I'VE BEEN DOING PYTHON FOR LESS THAN A DAY!?

Bruh thanks alot!! I was fugging trying to figure out how to print every item from a list

[danielhod]

Meanwhile me coding a full program to reverse a list in c 😐
