if loop repeating first if statement
<p>I'm trying to create a continuous question loop to process all my calculations for my nmea sentences in my project. For some reason only the first <code>if</code> statement is executed. What am I doing wrong? I'm still fairly new to python</p>

<pre><code>   if command_type == "$GPGGA" or "GPGGA" or "GGA":
        #define the classes
        gps = GPS()

        convertfile = ConvertFile()
        print_gps = PrintGPS()
        #do the deeds
        createworkbook.openworkbook(data)
        print_gps.process_gpgga_data(data)
        createworkbook.closeworkbook_gpgga(data)
