Python Python Basics Functions and Looping Create a Function

Trouble with Task 2

Great now that you have created your new square method, let's put it to use.

Under the function definition, call your new function and pass it the argument 3.

Since your square function returns a value, create a new variable named result to store the value from the function call.

squaring.py
def square(argument):
    try:
        return int(argument) ** 2
    except ValueError:
        return str(argument) * len(argument)

I am not sure what to do for this one.

I am asking you to use the function you just created.

The function is defined correctly, and I want you to call it with the value of 3. Since it returns a value, store it in a variable named result.

That make sense?

Craig, Ive written out the task and performed it correctly but when I go to run the square function it just spits out a syntax error near unexpected token. What am I doing wrong with this?

def square(number):
       return((number)**2)

result = square(3)

Hmm...wonder if it's those parentheses around that return statement. Try removing those. Return is a statement, not a function so you don't need to call it. Also the parents around number are not needed.

If you use the preview pane it'll tell you were the error is.

I'm away from a computer right now, but let me know if you are still stuck.

yeah so ive changed the code to

def square(number):
     return number**2

Result = square(3)

I ran it in treehouse:~/workspace$ python number.py and it returns back to treehouse:~/workspace$

I put it into the REPL as well and it just says invalid syntax line 1 python number.py ^ Im not sure what Im missing. Im guessing its something simple.

If you lowercase that Result to result it passes for me.

Is it not working for you on the challenge?

Thank you sir that seems to have done the trick.

Thank you sir, you're helping me a lot with this :D

it is asking to call the function, that you created and pass the argument 3, and then store the value in a variable called result.

3 thins you will have to know.

1) how do you call the function you created ? square

2)how to pass an argument into the call function ? square(3)

3) how to store the value from the result you get ? result = square(3)

This is what I came up with but it's not passing. def square(num): try: int(num) return(num * num) except ValueError: return(num * len(num))

square(num = num3) num3 = result

I was able to figure out task 1 but struggled with task 2. I don't comprehend why pass it to argument 3 equates square(3).

Hi Craig,

I am struggling a bit in deciphering the directions for this specific exercise. The exercise says, "Call your new function and pass it the argument 3. What does it mean when it says "pass it the argument 3?" I have no idea what that means. I saw people put (3) but I don't know why. I know that you need to commas to separate arguments, but I'm really confused on the verbiage. Apologies if my questions are vague.

Respectfully,

Mohammed Anam

I ran your code, and it did say, success, I am sure, that you have an issue to do with the indentation. next time, when you post your code, please the code formatting option, under markdown sheet.

def square(number): 
    value=(number*number) 
    return(value) 

result=square(3) 
print(result)

Thank you so much, Antonio is working perfectly right now.

Hello, I did my code and pass the first task and the second task failed. Can you please help me to figure out where I am doing the mistake. Here are my code

def square(number):
    value=(number*number)
    return(value)
    result=square(3)
    print(result)

def square(number): return number*number

result = square(3) print(result)

Hello everyone, this is my first post in the community and really struggled with this challenge but i eventually passed it, how ever looking back at the results others have been getting my code seems a little basic, but i still managed to pass it.

def square(number):
    return number * number

square(3)

result = square(3)

print(result)

Am i on the right track or was i way off here?

def square(number):
    return number * number
### square(3) This  part isn't needed.
result = square(3)
print(result)

Should get 9
