Small correction: In Tip 7 it should be - if currency in {"USD", "EUR"} - to use a set. So it must be curly braces and not parenthesis. Hope you enjoyed the video!

[@Sabre00]

I use this all the time with a List. Will change it to a Set moving forward. Excellent video as always!

[@BartDorlandt]

Isn't a tuple for effective for this. A set would only be useful when you want to enforce uniqueness. In this case a tuple is perfect.

[@NoProblem76]

I wonder what’s the performance difference in such a small collection between list set and tuple

[@dariuszspiewak5624]

In all earnest... There's no difference whether you use a list, a set,or a tuple here. There are just not enough elements to feel any difference. It'll start to show only when the number of elements goes into, say, hundreds or thousands.

[@olivermohr417]

you can also predefine standard_currencies = {"USD", "EUR"} outside the function to avoid the creation of the set each time the function is called

[@fullstackspiderman]

4:00: values are in a tuple/() not in a set/{}. Did you mean tuple or set actually?

[@qwertical]

You must have gotten the answer already, but I am just putting it here for the comments. It should be a set like he said, not a tuple like was shown.

[@name1355_0ne]

Thanks for the video, it was useful

[@learnwithraghuIT]

Dam, That's good. Look forward for more such videos

[@krystianprogress4521]

Thank you for this tips :)

[@fuckooo]

Thank you, some great tips here

[@patloeber]

Glad it was helpful!

[@ninjanape]

Thanks!

[@wilsvenleong96]

4:00 Isn't a set in Python initialized with curly braces?

[@patloeber]

Totally right, thanks for letting me know! I pinned a comment with the correction

[@inLofiLife]

"We should be always searching for opportunities to remove duplicated code" - now I know you're like me :) thanks for the tips!

[@tigrayrimey6418]

Nice tips, thanks. could you please do some python code implementation for the Passive-aggressive algorithm for the multiclass classification case?

[@patloeber]

thanks! Will have a look at that

[@saurrav3801]

Nice video bro..🔥🔥🤙

[@shaishai416]

amazing video...! please do more videos like that with refactore code, "code smell" I learn a a lot from that. and BTW the AI tool is nice... I you know more like this please let us know (:

[@manishcodeshala9639]

great video

[@bosadam3516]

Hi. Nice tricks I was trying 03:52 before I watch it :D currencies = ["USD", "EUR"] def process_payment(payment, currency): if currency in currencies: print(f"Payment: {payment} and currency is: {currency}") else: print(f"Global: {payment}") Thanks ^_^

[@patloeber]

nice!

[@ulissesalvesoffsec]

For tip #7, I would do like this so I don't need if's: payment_types = {"USD": process_standard_payment, "EUR": process_international_payment} def process_payment(payment, currency): payment_types[currency](payment)

[@sangchoo1201]

that's not the same code. video's code was "run standard_payment if currency is "CSD" or "EUR", otherwise run international one" but your code is "run different payment depend on the currency"

[@donnakillian1457]

Fascinating 😝😝😝 💖🔆🤪

[@_demonamv]

Which VS code theme don you use??

[@Mdroudian]

tabnine + sourcery = excellence =D

[@user-dm3qn7wv6v]

Tip 7. When checking if character is in string, should I convert a string into set?

[@MrDgf97]

Unless you’re checking a lot of characters, there’s no point. Turning a string into a set takes the same amount of time as just checking if a character exists in a string.

[@user-dm3qn7wv6v]

@@MrDgf97 thanks!

[@MrEo89]

Except “is_winning” is undefined.. so assuming most people would try these in repl and find them not to work, why not come out with better example?

[@sangchoo1201]

where's tip no.0? index not starting with 0?

[@toboletsgo6103]

4:02 you show tuple instead of set.

[@patloeber]

Yeah noticed this after the video :( thanks for the hint, I already pinned a comment

[@higheloguy9057]

Tip number 1 xD? For those people that cant tie their shoes.

[@patloeber]

Gotta start with a simple one 😂

[@natnaelkahsu8708]

can you make subtitles in german.

[@__________________________6910]

I know this except 5 and 8 points.

[@patloeber]

Great! At least you learned 2 new things :)

[@__________________________6910]

@@patloeber humm Thanks

[@Batman099]

tip number 1 is not even tip. 🧐 that's how people declared list.

[@patloeber]

had to start with an easy one :D but sometimes you still find this in other people's code...
