Safer, slower, and unnecessary.
There is no need for the nuclear-powered bulldozer of regular expressions
just to crack this tiny peanut. We can split on commas, and then strip
whitespace:
py> values = " 1.234 , 4.5678, 9.0123 ,4.321,0.9876 "
py> [s.strip() for s in values.split(',')]
['1.234', '4.5678', '9.0123', '4.321', '0.9876']
but in fact, we don't even need that, since float is perfectly happy to
accept strings with leading and trailing spaces:
py> float(' 1.2345 ')
1.2345
