from flask import Flask
app = Flask(__name__)
@app.route('/')
@app.route('/<name>')
def hello(name="treehouse"):
return 'Hello {}' .format(name)
I need help understanding why now an argument is now just adding a string inside
Def hello(name=“treehouse”):
Instead
Name= request.args.get(name,”treehouse”)

Once the route ’/<name>’ is added, the function needs to accept an argument from this route. So (name) is added.
However, since the original route ’/‘ is still valid, this will cause an error because this original route will call the function with no arguments when one is now required.
To prevent this missing argument error, a default is defined: (name=“treehouse”)
So, effectively, the route / is automatically turned into /treehouse.
Post back if you need more help. Good luck!!!
