What did I do wrong

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:num1>/<int:num2>')
def multiply(num1, num2):
    num1 = 5
    num2 = 5
    return '{} * {} = {}'.format(num1, num2, num1*num2)

Hey Ping!

Let's take a look at what the task is asking you to do. It wants you to add a view called multiply, give it a route '/multiply' and make it return the product of 5 * 5. So, first, let's create the correct route:

@app.route('/multiply')

Since it's asking you to assign values (5 * 5) to the variables, there is not need to set <num1>/<num2> at the route. Then, we can create the view:

@app.route('/multiply')
def multiply(num1=5, num2=5):
    return str(num1 * num2)

The thing to pay attention here is that you can only return strings in flask. So you have to parse the result for a string. And also, remember to assign the values 5 to both nums, since that's what the task is asking.

Cheers!

Hey Marta, this code is passing:

from flask import Flask

app = Flask(__name__)

@app.route('/multiply')
@app.route('/multiply/<int:num1>/<int:num2>')
def multiply(num1=5, num2=5):
    result = num1 * num2
    return str(result)
