7. Strings in Functions - Hello/Waynes?


#1

https://www.codecademy.com/courses/python-beginner-nzzVa/1/3?curriculum_id=4f89dab3d788890003000096#

I've been stuck with this exercise for about a month now, and it's starting to drive me mad. I've done all of the coding I think in necessary and every time I try to save and submit it, I get an error message saying either "Oops, try again. string_function('Waynes') returned 'Helloworld' instead of 'Waynesworld'" or "Oops, try again. string_function('Hello') returned 'Waynesworld' instead of 'Helloworld'".

This is supposed to be simple but I honestly don't know what I'm doing wrong


n = "Hello"

def string_function(s):
    s = "Hello"
    return s + "world"

print string_function(n)

Hi just remove the

 s = "Hello"

remenber that s is the argument so when you call the function with n(in which you already saved "Hello") it'll take the place of s
Hope that could help you

@textsurfer14861,
Have a read through the function talk
to get a feeling of what a parameter and/or argument is all about...
( also the consequence of using the return statement )

the FUNCTION talk

def myFunc( param1, param2):
    # Begin of =myFunc= FUNCTION-BODY
    # this =myFunc= function- has 2 PARAMETERS param1 and param2
    # param1 and param2 PARAMETERS are used 
    # as -local- VARIABLES throughout the =myFunc= FUNCTION-BODY
    print( param1 + " and " + param2 )
    #End of =myFunc= FUNCTION-BODY

If you want to call/execute the myFunc function
you will have to add a pair of parentheses to myFunc
like
myFunc()
As the myFunc function was defined
as having 2 parameters
you have to provide 2 arguments
in our case 2 string VALUES "Alena" and "Lauren"
like
myFunc("Alena","Lauren")

some quotes from the outer-world:

**argument is the value/variable/reference being passed in,
parameter is the receiving variable used within the function/block**

OR

**"parameters" are called "formal parameters",
while "arguments" are called "actual parameters".**

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
++++ function with 1 parameter using return-statement

def myFunction( param1 ):
    # //Begin of =myFunction= FUNCTION-BODY
    # //=myFunction= function has 1 PARAMETER param1
    # //this param1 PARAMETER is used as a -local- VARIABLE
    # //throughout the =myFunction= FUNCTION-BODY
    return param1;
    # //End of FUNCTION-BODY

You have defined a myFunction function
which takes 1 parameter param1
this param1 parameter is used
as a variable throughout the =myFunction= FUNCTION-BODY.

If you want to call/execute this myFunction function
and this myFunction function was defined
as having 1 parameter param1
you will have to provide 1 argument
in our case a "number VALUE" 4
myFunction( 4 )

some quotes from the outer-world:

**argument is the value/variable/reference being passed in,
parameter is the receiving variable used within the function/block**

OR

**"parameters" are called "formal parameters",
while "arguments" are called "actual parameters".**

============================================

As you are using the return-statement in your myFunction function
you will only get a return-value no-display.
You can however capture this return-value in a variable
and then use the print-method to do a display.

theResult = myFunction( 4 )
print theResult

OR directly

print myFunction( 4 ) .

I agree with wizmarco, I ran into this issue just now.
