How to remove or hide category list widget from home page or any other pages (without using a plugin)?

Question

Don't want to show the category widget or box.

Comments

"from home page or any other pages" => Did you mean "from all pages"?

Sorry for not being clear.  I thought the solution would be able to just remove the Categories widget / box code from any page and then I can decide if want to remove from which page later...but I guess Q2A doesn't work that way?

Hope its not too much trouble to ask for the solution for both if the solution is different?...I haven't decided if I want to remove just from home page or all pages.

I do want to remove that from all pages,how it is possible??
