sum of a string contains a sequence of decimal numbers [closed]

Question

I'm really a starter in programming. I want to prints the sum of a string s = '1.23,2.4,3.123'. I tried to use

total = 0.0
for s in '1.23,2.4,3.123':
    total += float(s)
print total

but it doesn't work, could anyone help? THX a lot

Answer 1

You could try the following:

total = sum(float(i) for i in s.split(','))

It runs like this:

• s.split(',') pulls out each 'number' in the string

• float(i) for i in s... makes a float of each split value

• sum() adds them all up

Hope this helps!
