extracting gpsd output from terminal using python program

Question

I did run a command from the python program which is related to GPS.

sudo gpsd /dev/ttyS0 -F /var/run/gpsd.sock
cgps -s

Now i want to use this information like latitude and longitude in my python code. How can i get these data? And these latitude and longitude values will be continuously varying. So can i get the value using python? Output from the above command gives like this

You can use regex:

Ex:

s = """

import re
print re.findall("(?:Longitude:).*(?=E )", s)
print re.findall("(?:Latitude:).*(?=N )", s)

Output:

['Longitude:   77.569187 ']
['Latitude:    12.945873 ']
