As I showed, .strip() is unnecessary. But float() is always necessary for
computing the sum and suffices indeed together with s.split() if s is just a
comma-separated list of numeric strings with optional whitespace leading and
trailing the comma:
print(sum(map(lambda x: float(x), s.split(',')))
Please trim your quotes to the relevant minimum.
