Do you know THIS about round() in Python??? 🤔

Everyone knows the round function, but do you know we can use negative values as argument?

Ugh. And there I was using some fancy % operation like a chump.

This is why I love python, been doing it daily for 5 years but still learn new ways of doing things. I also love the changes that are brought in with minor version changes

Another trick too, f"{val:.2f}", this will round to the two numbers after decimal point or what ever number u want

[grantpeterson]

"We all know that you can use a second argument in the round function-"
"I DIDN'T!"
thanks lol

And there I was three days ago writing a function doing this exact thing but with ceil. And I knew there was something like this already but maybe it doesn't work with math.ceil / floor

Thanks for sharing! I love sticking on your videos with The unexplored technicalities in python.

It's also can be applied on matlab. Same syntax too

[saitejam]

Awesome i didn't know that sir we want more tricks like this

[total_dk]

Try doing
round(0.5)
Then
round(1.5)
Have fun learning about this little feature in Python 😉

I wish Python gave access to all the rounding modes prescribed by IEEE754.

In the meantime, there is pyfenv ...

What's the name of that theme? Looks good

What I want built into a language is round to the nearest _. Not the decimals after. Being able to round to an arbitrary number helps a lot with grid operations.

I was just using the round function one day and got curious if it would give me an error if I tried and negative. I was pleasantly surprised when I saw that it did this

[labscience]

This was helpful, thanks. More videos like this please :)

[spencerlawrence]

That's so cool, I'm sure this'll come in handy at some point

[rondamon]

Cool. What happens is I pass a complex number?

[Rudxain]

I wish it had a 3rd parameter where you could specify the base or radix

[UsernameH]

I didn't know it go negative at least.

[innocent]

My request to you make a video that how to create a function that will make a newfolder using os module, if already exist then new folder 2 and then 3 or like this . Please short video No problem, I just couldn't finding this idea, and I am new in python.

[lolbor]

yes i used it for my last project, it's a lifesaver tbh
