A simple solution would be to save each line of data using JSON with the json
module:

>>> import json
>>> 
>>> 
>>> path = "x,y,z"
>>> varA = 12
>>> varB = "abc"
>>> line = json.dumps([path, varA, varB])
>>> print line
["x,y,z", 12, "abc"]
>>> loadpathA, loadvarA, loadvarB = json.loads(line)
>>> print loadpathA
x,y,z
>>> print loadvarA
12
>>> print loadvarB
abc
