Why is this code not working to sum the values in s??

Question

s='1.23 , 2.34 , 3.123'
ans=0
for i in s:
ans = ans + int(i)
print (ans)

Why is it bringing value error??

Answer 1

an other pythonic way to do the summation could be:
it's better to use a list instead of a string:

s=[1.23 , 2.34 , 3.123]
print(sum(s))

# if input can not be other than this, split and sum:

s='1.23 , 2.34 , 3.123'.split(',')
print(sum([float(i)for i in s]))

Answer 2

because s is a string and when you search a string with a for loop, you look at each induvidual character. '.' is not a number, so int('.') raises a value error
try:

s=[1.23,2.34,3.123]

Thanks y'all really appreciate 😊
