1. Being open source, many different ways have developed over the year for same function. This sometimes, creates chaos for others to read someone else code. - Being open source, many different ways have developed over the year for same function.

A function is called when the name of the function is followed by `()`. For the 'Hello, World!' example, the print function is called with a string as an argument for the first parameter. For the rest of the parameters the defaults are used. A function is called when the name of the function is followed by `()`.

Also the most important thing about python is that you don't have to specify the data type while declaring a variable, python's compiler will do that itself based on the type of value assigned.

The `objects` parameter is prefixed with a `*`, which indicates that the function will take an arbitrary number of arguments for that parameter. The `objects` parameter is prefixed with a `*`, which indicates that the function will take an arbitrary number of arguments for that parameter.
