I think you can do something like this, the key of the "parsing" is using the 
split function from the string module, 


<file data.dat>
aa juan
bb pedro
cc pablo
</file data.dat>


<PythonCode>
import string
myfile = "./data.dat"

liststr1 = []
liststr2 = []

for line in open(myfile, 'r').readlines():
    arrTmp = string.split(line, " ")
    liststr1.append(arrTmp[0])
    liststr2.append(arrTmp[1][:-1])  #  arrTmp[1][:-1] remove \n

print liststr1, liststr2

</PythonCode>

.i hope this helps .
