Pls help: Flask multiplication challenge step 5

I've completed the code step by step but stopped at step 5. The course just keep telling me 'It looks like Task 1 is no longer parsing....'

Actually I've run all these code in my PyCharm everything was fine. Don't know why the course checker can't pass it.

BTW, I just feel the task 5 description is not clear enough, I don't understand whether it requires only the multiplication result or also needs the formula.

from flask import Flask

app = Flask(__name__)

def multiply(num1, num2):
    return '{} * {} = {}'.format(num1, num2, num1*num2)

#app.run(debug=True, port=8000, host='')

I have same code with yours, but still doesn't work. Did you finally find the solution?

Hi Ker Zhang,

Task 1 had you add a '/multiply' route that took no arguments. You seem to be missing that now and you only have all the int/float combinations.

Also, in task 2 when you add the arguments to the view, they should have default values of 5.

def multiply(num1=5, num2=5):

And for the return value, it should be the result of the multiplication only as a string. If the arguments were 5 and 10 for example then it should return "50"
