Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
This solution relies on operators throwing a
TypeError
to check if the arguments are numbers. Deferring calculation using lambda functions would result incalculator('a','b','+')
incorrectly returning"ab"
instead of"unknown value"
.That being said, inputs like
calculator(3,0,'+')
would result in aZeroDivisionError
being thrown instead of the correct answer of3
.You should use lambda functions as the values in the dict so you don't precalculate all 4 ops.
Alr, could've probably guessed that but being more sure is always nice. Thx :D
One-time math calculations are normally
O(1)
, although it depends on how they are implemented.bruh what

красава просто лучший
it's already mentioned that only valid arguements will be passed

Вот небольшое пояснение:
"[aeiou]": Это регулярное выражение, которое соответствует любой гласной букве (в нижнем или верхнем регистре).
"": Это строка, на которую будет заменена каждая найденная гласная буква, то есть на пустую строку.
options: [.regularExpression, .caseInsensitive]: Эти опции указывают, что мы используем регулярное выражение (.regularExpression) и игнорируем регистр (.caseInsensitive), чтобы учесть гласные в любом регистре.
I think this is the best practice because we replace the rest of the letters with lowerCase
freaking genius
1 at the end is redundant
