Curly brackets ,Regular brackets and the Paranthesis

There is this dilemma in the web, The naming for various brackets. I took this course online called python in 2 hours, The instructor while going through tuples in collections he mistakenly calls '(' this a curly bracket, which I know probably most wont notice. But I feel this issue is everywhere. In almost every text book, the '(' is never spelt out or written in english, it's just '(', I know as long it serves it purpose nobody cares right. No! In this article I am gonna name them properly.

1. { } is called Curly Brackets

2. ( ) is called Paranthesis or Regular Brackets
