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(" ").

Some examples:

How do you import and use Spark-Koalas in palantir-foundry

Asked 2021-Apr-16 at 05:52

How can I -- in Palantir-foundry -- import and use the "Koalas: pandas API for Apache Spark" open source python package.

I know that you can import packages that don't exist through Code Repo and have done this, can I do this same process for Koalas package or do I need to follow another route?

...

ANSWER

Answered 2021-Apr-16 at 05:52

I was able to use Code Repo to upload a local clone of the package and then add the package in platform using the steps detailed here: How to create python libraries and how to import it in palantir foundry

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.
