Actually I'm trying to convert a string to a list of float numbers:
str = '53,20,4,2' to L = [53.0, 20.0, 4.0, 2.0]
As some of you suggested, using while it works:
-------------------------------------
L = []
file = ['5,1378,1,9', '2,1,4,5']
str=''
for item in file:
j=0
while(j<len(item)):
while(item[j] != ','):
str+=item[j]
j=j+1
if(j>= len(item)): break
if(str != ''):
L.append(float(str))
str = ''
j=j+1
print L
-------------------------------------
But I'm not sure this is an elegant pythonic way of coding :-)
Thanks for all suggestions!
