newbe how to read in a string? the solution

[William Famy]

Thanks for you answer.

This a sumary of the answer i receive. 
_________________________________________________
import string
     d,n1,n2,n3 = string.split(a, ",")
     n1 = float(n1)
     n2 = float(n2)
     n3 = float(n3)
 
 If the list of numbers is of variable length, this might be cool:
 
     import string
     seq = string.split(a, ",")
     for i in range(1, len(seq)): # this skips the 0 index,
         seq[i] = float(seq)      # which needs to stay a string.
_______________________________________________
One possibility:

import string

a='2000/12/28,24.3,87.1,65.4'
b = string.split(a, ',')

Then b[2] is 87.1,written as string: str(b[2])
_________________________________________________

strFields = a.split(",")
thirdField = strFields[2]
