Answer 1

you can use this function, adding a <br/> separator between each joke:

def jokes():
    jokes = pyjokes.get_jokes()
    jokes_final = "<br/>".join(jokes)
    return f'{jokes_final}'

or, you can use the render_template , pass the jokes list to it, and make a jinja loop to print each joke - better solution if you have complex html markup to add to the output

Answer 2

One way to do this would be to use jinja2's Template feature:

from flask import Flask
import pyjokes
from jinja2 import Template

app = Flask(__name__)

@app.route("/MultipleJokes")
def jokes():
    jokes = pyjokes.get_jokes()
    joke_template = Template("{% for joke in jokes %}<li>{{joke}}</li>{% endfor %}")
    return joke_template.render(jokes=jokes)
