float from numbers in text file

[davidgp]

hello,
i have a text file that contains gps coordinates that i want to load
into my mysql database
the file is basically in this format:
52.2375412
5.1802704

i basically tried this:
lat =0.0
for line in f:
  lat = float(line)

but this gives an error.. does anyone know what i should to do?
thanks,
