changing string to float

the challenge: Let's make sure we're always working with floats. Convert your arguments to floats before you add them together. You can do this with the float() function. I got the first two lines right, but can't change num1 and num2 to floats.

tried function(num1,num2) ....with and without quotes...between the two lines of code that are ok....no luck...... tired and trustrated

trial.py 
def add(num1, num2):
    return num1 + num2

"""python

def add(num1, num2):

try:

    add = int(num1, num2)

except ValueError:

    print("That's not a number")

else:

    return float(num1) + float(num2)

Hi Vedang.

The screen shot was missing the code that is above the screenshot.

I will do something even better. I am going to provide you the link to a workspace. https://w.trhou.se/dpxua8thzs

Once you open the workspace, choose the try.py on the left hand side.

Good Luck.
