Some really awful ways to build html elements in python. attributes with - in them not supported. Self-closing tags not supported. Comments not supported. Doctype strings not supported. attribute validation on tags not supported.

tags.py

# First approach, just make a function manually for every tag
# Then feed them all back to the same core html_element function for rendering
import inspect
import sys

def html_element(*args, **kwargs):
    tag = inspect.stack()[1][3]
    attrs = [f"{kwarg}=\"{kwargs.get(kwarg)}\"" for kwarg in kwargs]
    children = "\n".join([f"{child}" for child in args])
    return f'<{tag}{" " if attrs else ""}{" ".join(attrs)}>{children}</{tag}>'
