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.
What is wrong with my code?
from flask import Flask
app = Flask(__name__)
@app.route("/multiply")
@app.route("/multiply/<num1>/<num2>")
def multiply(num1=5, num2=5)
R = num1 * num2
return str(R)

The second error is less obvious. When the code is tested without num1 and num2 arguments, they get the default value of 5. But when the code is tested with /multiply/10/10, the value assigned to both num1 and num2 is the string "10". all URL arguments are passed in as strings. An error is thrown because you can't multiply two string.
Change the code to convert to strings. This will get you through Task 2
from flask import Flask
app = Flask(__name__)
@app.route("/multiply")
@app.route("/multiply/<num1>/<num2>")
def multiply(num1=5, num2=5): # <-- add missing colon
R = int(num1) * int(num2)
return str(R)
