The first thing I'd suggest is not to try to do it all in one step.
Break it into chunks and write helper functions for each part,
that will be much easier to debug.
I think you want a parser to extract the lat and lon values
as a tuple. A function to tidy up the lat and another to do
the lons. Finally a ms to decimal convertor.
Your top loop then becomes:
coords = []
for line in file(...):
lat,lon = getLatLon(line)
lat = latTidy()
lon = lonTidy()
coords.append((asDec(lat),asDec(lon)))
To produce a list of coord tuples in decimal format.
Now, can you solve the 4 sub problems?
A regex may help with the first one.
The second and third will need knowlege of each possible
format
The fourth is a straightforward math exercise
