implement a ".join(*args)" method

See original GitHub issue

It would be nice to have a DOMElement.join() method that mimics the str.join() method in python.

Ideally, this method would accept a list of things and returns the passed list with the chosen TemPy tag instances between the list elements just like the str.join method:

Br.join(["pizza", "pasta", "lasagna"])
>>> ["pizza", Br(), "pasta", Br(), "lasagna"]

Hr.join(["pizza", "pasta", "lasagna"])
>>> ["pizza", Hr(), "pasta", Hr(), "lasagna"]

Br.join(["pizza"])
>>> ["pizza"]

I’d make it a classmethod, so both Br.join(["pizza", "pasta", "lasagna"]) and Br().join(["pizza", "pasta", "lasagna"]) sytntaxes are allowed. In the latter syntax copies of Br() have to be created.

Hi,

I think by using ‘cls()’ first you are creating a new object of class and returning it.

Yes, this is ok to happen, we don’t want the same instance in between the elements of the input, but several new instances of the same class.

For instantiating an object we need parameters of init method

it’s ok to just init the class with no parameters ( cls() ).
