How to view my clicked solution(Best Practice, Clever) for my study?

thanks.

v1_per_second = 0.2
v2_per_second = 0.236111111111111

first test case return [0, 32, 19]
I want to return [0, 32, 18]

I think that floating point problem.
I tried round(v2_per_second, 2) to failed.

How about in python??

Sorry, I debuged with your source code.
I realized setdefault is only one saved in dictionary.
Yes. the other problem is exists.
Original problem: return first player
The other problem: return first, second player

How about?
In case

print(winner([c16, c17, c18])) #Rob, Gandalf
print(winner([c18, c17, c16])) #Gandalf, Rob

How about equal player??
dictionary is not ordered.
scores is dictionary that not ordered.

Clear!

"Same" means, here, that the elements in b are the elements in a squared, regardless of the order.

I forgot this statement. I have a low english skill then I skiped difficult statement.
I prefer code more than complicated statement.
Good luck!

function name is wrong

# wrong
def gruop_by_commas(n):
# correct
def group_by_commas(n):

plz change function name.

You had better think again.
I had same problem.

Point

• Use list range. ex) str_[:i]

How about works this function?
I'm curious this solution.

I compared time between you and me.
you: 100000 loops, best of 3: 9.61 µs per loop
I : 10000 loops, best of 3: 20.1 µs per loop

Need Features

1. How about code excute time?
2. How about code time complexity and space?

• ex: O(1) or O(n) or O(n log n) or O(n^2)

3. Need sort time complexity tab

Thanks.

Why TypeError occurred?

def prefill(n,v):
    print(n)
    print(v)
    
should work with n as 0
Traceback:
   in 
TypeError: prefill() takes exactly 2 arguments (1 given)

I didn't understand..
Why didn't into the function?
I think TestCase is wrong.
How about your think?

That's beginning from all my fault.

I would have explained detailed suggesttion.
Sorry for this accident.

I think bkaes just translate my opinions to you. but choose unproper words to you. I thknk that didn't insult meaning.

Back to the fact.

Fact

I think confused order

a = [121, 144, 19, 161, 19, 144, 19, 11] 
b = [11*11, 121*121, 144*144, 19*19, 161*161, 19*19, 144*144, 19*19]

I think corrected order

a = [11, 121, 144, 19, 161, 19, 144, 19] 
b = [11*11, 121*121, 144*144, 19*19, 161*161, 19*19, 144*144, 19*19]

How about g964 think?
I respect whatever Your choose.

I'm sorry for detailed description.
I wasn't attacked to you. @g964
Sure, I thank for you. because you used to make the problem with a lot of your valuable time.

But, I think example needs changed position then people know your purpose quickly.
Thanks for discussion and answer.

and thank you for your translate @bkaes.

Example is consued

a = [121, 144, 19, 161, 19, 144, 19, 11]
b = [11*11, 121*121, 144*144, 19*19, 161*161, 19*19, 144*144, 19*19]

I understand a[0] == b[0]. because I wasted a lot of my valuable time.
example needs changed position.
