[Swlug] Quick Pythom question.

[Rhys Sage]

After finding the GitHub code was very flaky with faked references to Baidu and Glonass satellites, I cleaned up the mess by removing a few yards of pointless code and the deleted the bit that read the satellite downstream before rewriting it... Here's my final solution which gives more data to the user, takes up less space and is actually commented.

    def L76X_Gat_GNRMC(self):
#we are only after the GNRMC field and only want:
# latitude, longtitude, direction, time and speed. Nothing else is of
# any importance - maybe data valid might be needed - don't yet know
        data = self.config.Uart_ReceiveString(BUFFSIZE)
        stringy = data.decode('UTF-8')
        StLen = len(stringy)
        if (stringy.find("$GNRMC") >-1):
#crop everything before the first field
            StartPoint = stringy.index("$GNRMC")+7
            stringy = stringy[StartPoint: (StLen - StartPoint)]    
#crop everything from the second $        
            EndPoint = stringy.index("$")
            stringy = stringy[0:EndPoint]
#now make it into a list
            Listy = stringy.split(',')
            RSTime = Listy[0]
            RSValid = Listy[1]
            RSLattitude = Listy[2]
            RSNSHemisphere = Listy[3]
            RSLongtitude = Listy[4]
            RSWEHemisphere = Listy[5]
            RSGroundSpeed = Listy[6]
            RSDirection = Listy[7]
            RSDate = Listy[8]
            RSVariation = Listy[9]
            RSChecksum = Listy[10]
#now return the required values to the program. That, for the drone operation will be
            return RSTime, RSLattitude, RSLongtitude, RSGroundSpeed, RSDirection, RSDate, RSVariation
