HTML Generator
You are writing a script that generates HTML for a webpage on the fly. So far, you have written two decorators that will add bold or italics tags to any function that returns a string. You notice, however, that these two decorators look very similar. Instead of writing a bunch of other similar looking decorators, you want to create one decorator, html(), that can take any pair of opening and closing tags.
def bold(func):
@wraps(func)
def wrapper(*args, **kwargs):
msg = func(*args, **kwargs)
return '<b>{}</b>'.format(msg)
return wrapper
def italics(func):
@wraps(func)
def wrapper(*args, **kwargs):
msg = func(*args, **kwargs)
return '<i>{}</i>'.format(msg)
return wrapper
