Hey, how do ou solve the challenge on multiply view: Add a view named multiply. Give multiply a route named /multiply.

Add a view named multiply. Give multiply a route named /multiply. Make multiply() return the product of 5 * 5. Remember, views have to return strings.

flask_app.py
from flask import Flask

app = Flask(__name__)

@ app.route('/<multiply>/<int:num5>/<int:num5>')
def multiply(num5, num5)
 return '{} * {} = {}'. format (num5, num5, num5*num5)

Hi there, Erwan Mba Mba! I can see that you've put a good deal of effort into this, but a few things are going on here. First, you have some syntax errors. Namely, you're missing a colon : after the def multiply, and there is a space between @ and app. You may not have the space, and you must have the colon.

Secondly, you're doing a little more than they're asking you to right now. Right now, they want a route named multiply that takes no numbers and always returns the result of the multiplication of 5 times 5. So it's a little hard-coded at the moment, but you'll be building that out as you go through the challenge so that it'll be flexible. Also, it's just asking you to return "25" not "5 x 5 = 25". Remember that when these challenges are checking for strings, they must be exact matches.

from flask import Flask

app = Flask(__name__)

@app.route('/multiply')  # define the route
def multiply():  # define multiply with no parameters
    return '{}'.format(5*5)  # always returns 25 as a string

Hope this helps! :sparkles:
