technical interview prep: Python basic

Question

i can't seem to find out why it keeps saying incorrect
```formatting.py
city = ("Kansas ")
teamname = ("City Royals. ")
def cheer(city, teamname):
    return ("Let's go, ", city, teamname, "Let's go!")
```

Hi Leslio! When I ran your code in the challenge, I saw this error message:
~~~python
AssertionError: ("Let's go, ", 'Kansas City', 'Royals', "Let's go!") != "Let's go, Kansas City Royals. Let's go!" : 
Uh oh, I didn't get the correct string returned. It should have been 'Let's go, Kansas City Royals. Let's go!'
~~~
The program is looking for this exact string:
~~~python
"Let's go, Kansas City Royals. Let's go!"
~~~
Whereas your code is returning this:
~~~python
"Let's go, ", 'Kansas', 'City Royals', "Let's go!"
~~~
I would wrap your entire return statement in one quotation mark, and I would use {curly brackets} to format the city and team name in your statement. Like this:
~~~python
def invitation(day, address):
    return("I'm having a party on {} this week. You should come! My address is {}.".format(day, address))
~~~
That way, your arguments won't have quotation marks around them when your function is returned (and you'll have an exact match.)
PS- you don't have to define the city and teamname before you write out the function. When you click "Check Work" on the challenge, the Treehouse Program calls your function and passes in arguments (you just don't see it.)
It does this:
~~~python
def invitation(day, address):
    print("I'm having a party on {} this week. You should come! My address is {}.".format(day, address))
invitation("Tuesday", "123 Main Street")
^ It calls your function and passes in the arguments. It uses "Kansas City" for the city and "Royals" for the teamname. That's why you see that team specifically in the error message.
