python - How do I make an exception for a blank space so it would not output a 0?

Question

How do I make an exception for blank spaces so it would not ouput 0. It's only outputting the "total" itself.

 line = input("Enter a line of numbers - separate them with spaces: ")
    strings = line.split()
    total = 0
    try:
        for substr in strings:
            total += float(substr)
        print("The total is:", total)
    except:
        print(substr, "is not a number.")

Answer 1

# line = input("Enter a line of numbers - separate them with spaces: ")
line = '1 1 b 1 1 11 1 666'
strings = line.split()
total = 0

for substr in strings:
    try:
        total += float(substr)
    except:
        print(substr, "is not a number.")
print("The total is:", total)

or

for substr in strings:
    if substr.isnumeric():
        total += float(substr)
print("The total is:", total)
