-| Here is a quick solution. Warning untested code ;-)
-| 
-| import string
-| 
-| def line2floats(theLine):
-|   # useful to convert a string to a tuple of floats
-|   f1,f2 = string.split(string,strip(theLine),' ')
-|  return float(f1),float(f2)
-| 
-| file = open('data.txt','rb')
-| lines= file.readlines() # this should return a list of string, one string
-| per line.
-| floats = map(lambda eachLine: line2floats(eachLine), lines) # line2floats is
-| defined below..
-| 
-| print floats
-| 
-| so if you had:
-| 1.02 2.03
-| 3.04 4.05
-| 
-| floats will be equal to [(1.02,2.03),(3.04,4.05)]
-| 
-| I hope this will help you
-| 
-| Cheers,

Similar solution using list comprehensions:

	>>> import string
	>>> f=open('foo.txt')
	>>> floats=[ string.split(i.strip(),' ') for i in f.readlines() ]
	[['1.02','2.03'], ['3.04','4.05']] 
	>>>
