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.
