            Replace commas with spaces ? Fisher-Yates randomization
            Asked 2021-Jun-09 at 07:57

            Thanks to @axtck for the help for the Fisher Yates randomization, he helped me to change number into words here :

            Since the shuffle functions shuffle the arrays indexes, you can just shuffle the array the same way you did but add name strings in the array.

            The code is now showing a string of words with commas as separation between the words, its working well!

            Now I want to replace commas, with spaces (example : Histoire Chien Koala Arbre Italique Lampadaire Docteur Boulet Maison Forge Gagnant Ennui)

            Can somebody help me to change these commas with blank spaces?

            Thanks

            Calling toString() on an array will return the string representation of the array which is item1,item2,....

            If you want to join the array in another way, you can use array method join(), it takes a separator string, which in your case would be a space join(" ").

            However, shortly afterwards Palantir admins introduced an update which included the Koalas package as a native package to the platform. I have not however had time to try using this for any major tasks as of yet.
