Can't use try ,except,else in the proper place

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

Here's an example. Yours is missing logic to attempt in the "try" portion of the block. Note the use of finally, which is actually seldom used in the real world, but it's worth knowing about. The type error is raised because the sum function cannot add a string type with an integer. 

def add_vals(val1, val2):
  try:
    return sum(val1, val2)
  except TypeError:
    return('You have a type error check your args')
  except ValueError:
    return('You have a value error check your args') 
  finally:
    print('this is always gonna get called')


print(add_vals(1, 'dog'))


>>this is always gonna get called
>>You have a type error check your args
