TypeError: Can't convert 'int' object to str implicitly

I need help with the code below, I keep getting "TypeError: Can't convert 'int' object to str implicitly"

Not sure what I'm doing wrong.

Thank you!

def add(num1, num2): try: (num1 + num2) except ValueError: return none else: return (float(num1) + float(num2))

trial.py 
def add(num1, num2):
    try:
        (num1 + num2)
    except ValueError:
        return none
    else:
        return (float(num1) + float(num2))

You want to do num1 = float(num1) num2 = float(num2) in your try block, not in your return statement. Also your return statement in your except block returns none (which will cause an error since there is no variable named none). When writing None, True, or False in Python, you always capitalize the first letter.
