There are several possibilities:-
1) the simplest is simply a lsingle line
with the values separated by some character - commas, colons,
hyphens, whatever doesn't appear in the data.
Then read the line as a string, split(char) it into its parts and
the parts to the appropriate types. Using commas may allow you
to leverage the CSV module.
2) Use a richer format, like XML which provides for very
complex structures and allows you to use a standard parser
like ElementTree to extract the data.
3) Write all values onm their own lines and add a marker to
separate lists. Then use a while loop to read in the lines until
you reach the marker.
Thee are other options too, but those should be enough
to get you going.
