@100rabhh : Just put these lines to your code:
from nmeaParser import NmeaParser
#Create NMEA structure
nmea = NmeaParser()
#..then send your uart input to the library
if gps_uart.any():
nmea.update(gps_uart.readline())
#...then you can access your data by
print ('Latitude: ' + str(nmea.latitude))
print ('Longitude: ' + str(nmea.longitude))
print('Altitude:'+ str(nmea.altitude))
#...there are several other data available, just check the parser code for more info
