String Distance Matrix in Python -


how calculate levenshtein distance matrix of strings in python 

              str1    str2    str3    str4    ...     strn       str1    0.8     0.4     0.6     0.1     ...     0.2       str2    0.4     0.7     0.5     0.1     ...     0.1       str3    0.6     0.5     0.6     0.1     ...     0.1       str4    0.1     0.1     0.1     0.5     ...     0.6       .       .       .       .       .       ...     .       .       .       .       .       .       ...     .       .       .       .       .       .       ...     .       strn    0.2     0.1     0.1     0.6     ...     0.7

using ditance function can calculate distance betwwen 2 words. here have 1 list containing n number of strings. wanted calculate distance matrix after want clustering of words.

just use pdist version accepts custom metric.

y = pdist(x, levensthein)

and levensthein can use implementation of rosettacode suggested tanu

if want full squared matrix use squareform on result:

y = np.squareform(y)

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
