Getting invalid syntax, and I'm not sure why

This is my code:

total = 0

s = "helloV"

for i in range(0, len(s)):
    total += 4 if s[i] == "V" else (total += 9) # The line where I'm getting the syntax error.

I'm not sure why this code is giving me a syntax error. Any help would be appreciated.

The code should be like this:

total = 0

s = "helloV"

for i in range(0, len(s)):
    total += 4 if s[i] == "V" else 9

When the if condition is true add 4 else add 9.

total = 0

s = "helloV"

for i in range(0, len(s)):
    if s[i] == "V":
        total += 4
    else:
        total += 9

Above is a clear way to solve the syntax issues.

You could also do something like this if you are looking for shorter code. It just uses a list comprehension that makes a list that has a 9 if the character in s does not equal 'V', and 4 if it does. Then, it just sums the resulting list with sum():

s = "helloV"
total = sum([4 if i == 'V' else 9 for i in s])

Or you could use map() to just apply a lambda function to every element of s that does the same thing as explained above:

s = "helloV"
total = sum(map(lambda i: 4 if i == 'V' else 9, s))
