*args and **kwargs in Python
Python interview exercise on Functions & Decorators, difficulty 2 of 3. Solve it in the editor beside a worked example, or cold in Interview mode with the example hidden; the tests run the moment you do.
Write make_tag(name, *children, **attrs) that builds an HTML element as text: the attributes in the order given, then the children joined together, then the closing tag.
make_tag("a", "home", href="/") → '<a href="/">home</a>'
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Interview mode hides the example: solve it from memory, without the hint or the solution, and it counts as solved cold. Progress is saved in your browser, and in your account if you sign in.
