I'm trying to plot a series of points/locations on a map. I'm reading the
latitudes and longitudes from a file, with each lat, lon pair on each record
(line). Here is the code:
def make_float(line):
lati, longi = line.split()
return float(lati), float(longi)
my_dict = {}

To clarify, you are trying to read in a set of (lat,lon) points in a file
that is space delimited, store the data, and then put a text marker at each
point, with each point numbered in order? The critical part is that you
want to use a list (or numpy array) instead of a dictionary. Something

many values to unpack
There are 203 records in the data file. Line 319 of test.py is this:
(lat,lon)=line.strip().split(' ')

To clarify, you are trying to read in a set of (lat,lon) points in a file
the '-' be causing a problem? I need to input
the lat, lon as in the file as shown above.

Have to say I whole-heartedly agree with Glenn. One

On second thought, the code requires basemap package too.

command and
paste them into the source code. Not ideal but will get the job done.
