Something like that:

Python 2.6.5 (r265:79063, Oct  1 2012, 22:07:21)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> a=[1,3,5,6,10]
>>> b=['a', 't', 'q', 'r', 's']
>>> sta = " ".join([str(i) for i in a])
>>> stb = " ".join(b)
>>> txt = "a " + sta + '\nb ' + stb
>>> f = open('test.txt', 'w')
>>> f.write(txt)
>>> f.close()
>>> f = open('test.txt', 'r')
>>> for line in f:
...     print line
...
a 1 3 5 6 10

b a t q r s
>>>
