Python K-Means Z-Transfrom : i want to use the k-means to cluster my results, but I have a lot of question.
<http://scikit-learn.org/stable/modules/generated/sklearn.cluster.KMeans.html#sklearn.cluster.KMeans>

My input data looks like this: 

`ID ABC XYZ UVW MSE 
10  A   X   U  102000
12  B   Y   V  9000`

Do I transform my data set in z-tranfromation?
Because I have numbers and character...

When i get result of Kmeans, should i run it often to crosschecking my results?

I want to know which ID is in which cluster. How i get this infromation out of software?

Thx in Advance.
