One way:
sage: f = open("mydatafile.txt")
sage: l1 = f.readline()
sage: ls1 = l1.split(" ")
sage: l1; ls1
"'b' 'breadth of member' 250\n"
["'b'", "'breadth of member'", '250\n']
sage: eval(ls1[2])
250
where mydatafile.txt is in $SAGEROOT and consists of these lines:
'b' 'breadth of member' 250
'D' 'overall depth of member' 550
and each item is separated by 2 spaces.
