i pass this kata but still dont understand how. i got an error in JupyterLite

"Expected 2D array, got 1D array instead: 
array=[0. 0. 0. 0. 0. 0. 0.].
Reshape your data either using array.reshape(-1, 1) if your data has a single feature or array.reshape(1, -1) if it contains a single sample." 

try to add .reshape(-1, 1) to X_train and got waring and the output:

/lib/python3.12/site-packages/sklearn/ensemble/_weight_boosting.py:519: FutureWarning: The SAMME.R algorithm (the default) is deprecated and will be removed in 1.6. Use the SAMME algorithm to circumvent this warning.
warnings.warn(
(AdaBoostClassifier(n_estimators=3, random_state=0),
 array([0., 0., 0.]),
 array([1., 1., 1.]))

i dont understand why it happend because clf.fit(X, y) -> X
{array-like, sparse matrix} of shape (n_samples, n_features); y
array-like of shape (n_samples,) my X, y: X -> 1d array and y -> is 1d array

python new test frameworks

what about this ?

The entries() method of Map instances returns a new map iterator object that contains the [key, value] pairs for each element in this map in insertion order.

Good one!

Eh, realistically it'd be the same generator with one less parameter anyway.

Next time I would prefer that instead of relying on implementation details such as ordered dicts/Maps you simply provide an array of tuplies (i.e. the result of functions.entries() in JS). the V8 engine happens to also have ordered Maps and Sets, but that is not guranteed to happen in other JS engines.

Some. :] I checked diffs, glanced at the example solution and example tests, looked at the random tests and decided not to look too hard ( you obviously worked from the Python tests. I simplified quite a bit for Haskell and JS, because I don't think highly biased tests add much value ), and approved.

That might be a new record lmao.

How much of it did you sanity check?

Approved

technically, all the keys are positive, afaik (...or 0, yeah). But that's a pointless requirement, yes.

the goal is to sort the numbers IN PLACE

No, it is to group the numbers. Sorting in place is something entirely different.
