Can anyone find the error in this code? It does not pass the challenge and I have tired about 15 variations with no effect.
from flask import Flask
app = Flask(name)
@app.route('/multiply/<int:num1>/<int:num2>') @app.route('/multiply/<float:num1>/<float:num2>') @app.route('/multiply/<int:num1>/<float:num2>') @app.route('/multiply/<float:num1>/<int:num2>')
def multiply(num1, num2): #return 5 * 5 return '{} * {} = {}'.format(num1, num2, num1*num2) #return str(num1*num2) app.run(debug=True, port=8000, host='0.0.0.0')
from flask import Flask
app = Flask(__name__)
@app.route('/multiply/<int:num1>/<int:num2>')
@app.route('/multiply/<float:num1>/<float:num2>')
@app.route('/multiply/<int:num1>/<float:num2>')
@app.route('/multiply/<float:num1>/<int:num2>')
def multiply(num1, num2):
#return 5 * 5
return '{} * {} = {}'.format(num1, num2, num1*num2)
#return str(num1*num2)
app.run(debug=True, port=8000, host='0.0.0.0')

Treehouse Guest Teacher- You shouldn't have a blank line between your decorators and the function they decorate
- You no longer have a route for just
/multiply. That shouldn't ever go away - You need to always return the product of the numbers, not the mathematical sentence
- IIRC,
num1andnum2should default to 5
If you're getting a timeout or it's just sitting there, that's because of the app.run() at the bottom. I don't think I'm able to catch and remove those, but I'll look into it tomorrow.

11,940 PointsI changed it to this, but it is still not running from flask import Flask
app = Flask(name)
@app.route('/multiply') @app.route('/multiply/<int:num1>/<int:num2>') @app.route('/multiply/<float:num1>/<float:num2>') @app.route('/multiply/<int:num1>/<float:num2>') @app.route('/multiply/<float:num1>/<int:num2>') def multiply(num1, num2): return str(num1*num2)
The error I am getting is Didn't return a 200 at /multiply

Treehouse Guest TeacherYou need default values for num1 and num2.

11,940 PointsHere is this iteration of my code from flask import Flask from flask import render_template
app = Flask(name)
@app.route('/multiply/') @app.route('/multiply/<int:num1>/<int:num2>') @app.route('/multiply/<float:num1>/<float:num2>') @app.route('/multiply/<int:num1>/<float:num2>') @app.route('/multiply/<float:num1>/<int:num2>') def multiply(num1=5, num2=5): return str(num1*num2)
I have tried also the following: def multiply(num1="5", num2="5"):
def multiply(num1=int("5"), num2=int('5"):
return num1*num2
Can you just send me the actual code? I am just too stuck.

Kenneth Love
Treehouse Guest TeacherYou've almost got it. You have to return a string, so return str(num1*num2). And the defaults need to be ints, not strings like your last examples. I'm just on my phone right now but I can post better code answers tomorrow

11,940 PointsTurns out that the extra / on the multiply route was the problem.

11,940 PointsI tried with this lines added at various times: @app.route('/multiply') or without app.run(debug=True, port=8000, host-'0.0.0.0')
