Could you please help me with this task:
"You're doing great! Just one more task but it's a bigger one.
Right now, we turn everything into a float. That's great so long as we're getting numbers or numbers as a string. We should handle cases where we get a non-number, though.
Add a try block before where you turn your arguments into floats.
Then add an except to catch the possible ValueError. Inside the except block, return None.
If you're following the structure from the videos, add an else: for your final return of the added floats."
Is there anything like hints for these tasks? Thanks
def add(num1, num2):
return float(num1) + float(num2)
try:
count = float(input("Give me a number: "))
except ValueError:
return None
else:
return float(num1) + float(num2)

A couple of issues.
You need to use this line of code for your try block, to let Python know that's the code your checking errors for.
return float(num1) + float(num2)
Also make sure the try block is indented as this is part of your function. You're almost there! :-)
