13,496 PointsI would simply not specify what data type I wanted in the route. This would therefore give me string values, from there simply use a try except to accept both ints and floats.
Example:
@app.route("/add/<num1>/<num2>") # NOTE: This gets the values as strings
def add(num1, num2):
num1 = getValue(num1) # Get int or float values for both
num2 = getValue(num2)
return "{} + {} = {}".format(num1, num2, num1 + num2)
def getValue(string):
try:
return int(string) # Attempt to return int value of string
except ValueError: # If getting int value failed, then get float value
return float(string)
Note:
The getValue() function was created to demonstrate the logic separately but it could have been added within
def add(num1, num2):
```.
It is however cleaner and more importantly, reusable.

Courses Plus Student 1,390 PointsI wonder if there is any way that we can use to specify num1 can be either int or float in a single route instead of repeat for several routes

Python Web Development Techdegree Graduate 33,011 Pointsdo you mean pass different datatypes as arguments?
python
@app.route('/add/<int:num1>/<int:num2>')
@app.route('/add/<int:num1>/<float:num2>')
@app.route('/add/<float:num1>/<int:num2>')
@app.route('/add/<float:num1>/<float:num2>')
def add(num1,num2):
return "{} + {} = {}".format(num1,num2,num1+num2)
